Stannous chloride, also called tin(II) chloride, is an inorganic tin compound with the formula SnCl2. Its most important industrial characteristic is its ability to act as a reducing agent, making it useful in chemical synthesis, surface treatment, analytical work, and other processes that require tin in the +2 oxidation state. Buyers commonly encounter anhydrous stannous chloride and its dihydrate, SnCl2·2H2O; the appropriate form depends on process requirements, handling conditions, and the product specification.

This guide explains the compound’s key properties, compares its common forms, and outlines where it may be used. It also provides a practical framework for evaluating grade, documentation, packaging, and supplier support. Because actual requirements vary by application, confirm the intended use and specification with your technical and procurement teams before ordering.
This guide is intended for chemical buyers, process engineers, formulators, laboratory managers, and manufacturers assessing stannous chloride for a defined application. It can also help procurement teams prepare a technically complete request for quotation. It is not a substitute for a product-specific safety data sheet, operating procedure, or regulatory review.
Stannous chloride contains tin in the +2 oxidation state and is generally valued for its reducing behavior and its role as a soluble or reactive tin source, depending on the process conditions. The anhydrous compound has a molar mass of approximately 189.60 g/mol, while the dihydrate has a molar mass of approximately 225.63 g/mol. These values matter when calculating charge quantities because a kilogram of each form does not contain the same molar amount of SnCl2.
Anhydrous stannous chloride is reported to have a melting point of about 247 °C. Physical properties can differ between anhydrous material and hydrated material, and specifications should identify the supplied form rather than relying on the name alone. For exact handling and storage information, consult the supplier’s current technical documentation and safety data sheet for the product being purchased.
Anhydrous stannous chloride is the water-free form and may be suitable where a process requires control over water introduced with the reagent. The dihydrate contains two water molecules per formula unit and is commonly selected for processes designed around that hydrated form. The choice affects calculations, handling, and potentially the behavior of a formulation, so users should confirm whether specifications are expressed on an as-supplied or an anhydrous basis.
Stannous chloride can be sensitive to moisture and air exposure, and aqueous solutions may undergo oxidation or hydrolysis depending on conditions. Acidic conditions are often used in solution preparation to help maintain tin in the +2 state, but suitable conditions depend on the application. Do not assume that a solution prepared for one process will remain stable or perform appropriately in another.
Stannous chloride is used in chemical reactions where a reducing agent or a tin(II) reagent is required. Its role may include reducing selected chemical species or providing tin for a subsequent reaction step. The suitability of the material depends on reaction chemistry, solvent or solution conditions, impurity tolerance, and the required control of oxidation state.
In metal finishing and related surface-treatment processes, stannous chloride may be used as a tin source or as part of a process sequence involving deposition or surface preparation. The exact use depends on the bath formulation and operating controls; the compound should not be assumed to function as a complete plating bath by itself. Buyers should discuss concentration, compatibility, replenishment practices, and process-specific impurity limits with their technical team.
Stannous chloride has been used as a mordant or reducing agent in certain textile and dye processes. Its role is application-specific, and its suitability can depend on the fiber, colorant, process conditions, and applicable environmental or product requirements. Manufacturers should verify performance at process scale and assess waste handling requirements before adopting it.

Laboratories may use stannous chloride as a reagent in analytical procedures and chemical preparation. For these applications, purity, trace-metal limits, consistency between lots, and clear documentation may be more important than bulk price alone. Buyers should identify the method or intended analytical use when requesting a grade recommendation.
Start by describing what the material must do: provide tin, act as a reducing agent, support a surface-treatment process, or serve as an analytical reagent. Include the process medium, operating conditions, and the consequences of a change in impurity or water content. This helps distinguish a technically appropriate product from one that merely shares the same chemical name.
State whether you require anhydrous stannous chloride or the dihydrate. Then define the required assay basis, relevant impurity limits, particle or appearance requirements if applicable, and the test methods or documentation needed for acceptance. If you have an existing approved specification, provide it for supplier review rather than relying on a generic description such as “industrial grade.”
Ask how the product is packed, protected from moisture, labeled, and stored during shipment. Packaging should fit the receiving facility’s storage conditions, handling equipment, and consumption rate. Confirm that the proposed package size and transport arrangement are compatible with the product’s safety requirements and local regulations.
Request current product documentation, including a technical specification and safety data sheet, and confirm what lot-specific quality documents are available. For recurring use, discuss expected order frequency, forecast volumes, delivery locations, and any change-control or traceability requirements. A clear supply discussion can help identify commercial or logistics constraints before they affect production planning.
Stannous chloride pricing is not determined by chemical identity alone. The requested form, grade, purity and impurity limits, order quantity, packaging, destination, and current logistics conditions can all affect a quotation. Minimum order quantities and lead times may also vary by product availability and shipment requirements, so buyers should request current terms rather than assume a standard figure.
To support an accurate quotation, provide the required form, specification, estimated quantity, packaging preference, delivery destination, and target delivery window. If the material is for a qualification or trial, state that clearly and ask whether a suitable evaluation quantity can be offered. A supplier can then confirm feasibility and identify any documentation or handling information needed for the transaction.
Azeal Materials supports B2B buyers evaluating stannous chloride for industrial and laboratory requirements. We can review the requested product form, specification, quantity, packaging, and destination to clarify whether a supply option is suitable for your inquiry. Product availability, documentation, and commercial terms should be confirmed for each order.
Stannous chloride is used across chemical, surface-treatment, textile, and analytical applications because it supplies tin in the +2 oxidation state and can serve as a reducing reagent. The right choice depends on the intended process and whether anhydrous material or the dihydrate is required. Form, purity, moisture control, solution conditions, and documentation all deserve review before purchase.
For your next step, prepare the application, required form, specification, quantity, packaging preference, and delivery destination. Share those details with Azeal Materials to request product information and a quotation. Confirm technical suitability with your process team and consult the product-specific safety documentation before handling or use.
