Description

Barium Hydrosulfide is an inorganic salt primarily used as a key reagent in chemical synthesis and industrial processes. Its value lies in its role as a source of hydrosulfide ions, which are essential for precipitation reactions and the synthesis of sulfur-containing compounds. This product is critical for industries such as chemical manufacturing, metallurgy, and water treatment, where precise control over sulfide chemistry is required. CAS NO 25417-81-6.

Application

• Chemical Synthesis: Acts as a precursor for the production of other barium salts and sulfur-based chemicals.
• Metallurgical Processing: Used in ore flotation and as a precipitating agent for the recovery of specific metals from solutions.
• Water Treatment: Employed in specialized applications for heavy metal precipitation and sulfide control.
• Analytical Chemistry: Serves as a laboratory reagent for qualitative and quantitative analysis involving sulfide ions.
• Textile Industry: Utilized in specific dyeing and finishing processes that require sulfide intermediates.
• Leather Processing: Applied in certain tanning operations as a depilatory agent or chemical intermediate.

Quality Control

Our Barium Hydrosulfide is manufactured under strict quality protocols to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including assay by titration and impurity profile analysis. A Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry, and well-ventilated area. The container must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can degrade the product. Recommended storage temperature is 15-25°C.
