Description

Stannouscitrate CAS NO 59178-29-9 is a specialized organotin compound, specifically the citrate salt of stannous (tin(II)) ions. This chemical is valued for its unique combination of tin's reducing properties and citrate's chelating ability, making it a critical reagent in advanced material synthesis and stabilization processes. It is primarily sought by manufacturers in the electronics, polymer, and specialty chemical industries for applications requiring controlled oxidation states and metal complexation.

Application

• Catalyst Precursor: Used in the synthesis of polymers and fine chemicals where tin-based catalysts are required.
• Electroplating & Surface Treatment: Serves as a key component in tin alloy plating baths for electronic components and corrosion-resistant coatings.
• Polymer Stabilizer: Acts as a heat and light stabilizer in specific PVC and other halogenated polymer formulations.
• Chemical Intermediate: Employed in organic synthesis for reduction reactions and the preparation of other organotin compounds.
• Glass Coating & Ceramics: Used in the formulation of conductive coatings for glass and in ceramic glazes.
• Preservative & Antioxidant: Functions in specialized industrial systems where its reducing properties prevent oxidative degradation.

Quality Control

Our Stannouscitrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, metal content, and impurity profiles. Certificates of Analysis (COA) detailing results for assay, heavy metals, and other critical parameters are provided with every shipment to guarantee traceability and consistency for your industrial processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and oxidation.
