Description

Sodium Hydrosulfide Hydrate is a versatile inorganic salt widely used as a sulfiding and reducing agent in industrial processes. Its commercial importance stems from its ability to efficiently introduce sulfide ions and act as a powerful nucleophile in chemical synthesis. This compound is essential for manufacturers in sectors such as pulp and paper, leather processing, and mineral flotation, where controlled sulfur chemistry is required. We supply high-purity Sodium Hydrosulfide Hydrate CAS NO 207683-19-0 to meet the stringent demands of global industrial applications.

Application

• Pulp and Paper Industry: Used in the kraft process for delignification and as a source of sulfide in pulping liquors.
• Leather Processing: Acts as a key depilatory agent in the unhairing of hides and skins.
• Mining and Mineral Processing: Employed as a sulfidizing agent in the flotation of oxide copper and lead ores.
• Chemical Synthesis: Serves as a nucleophile and reducing agent in organic synthesis for the production of pharmaceuticals and agrochemicals.
• Water Treatment: Utilized for the precipitation and removal of heavy metal ions from industrial wastewater.
• Textile Industry: Applied in sulfur dyeing processes for cellulosic fibers.
• Copper Etching: Used in the printed circuit board (PCB) manufacturing process.
• Analytical Chemistry: Functions as a reagent in qualitative inorganic analysis.

Quality Control

Our Sodium Hydrosulfide Hydrate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including assay, moisture content, and impurity profile analysis. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We adhere to relevant industrial standards and can support compliance requirements for global markets.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide. Store away from strong acids and oxidizing agents. Recommended storage temperature is 15-25°C.
