Description

Barium Hydrosulfide Tetrahydrate is an inorganic salt compound primarily used as a precursor in chemical synthesis and industrial processes. Its value lies in providing a source of both barium and hydrosulfide ions under controlled conditions, which is critical for specialized manufacturing. This product is essential for industries such as chemical manufacturing, metallurgy, and research & development. CAS NO 12230-74-9.

Application

• Chemical Synthesis: Acts as a key reagent in the production of other barium compounds and specialty inorganic chemicals.
• Metallurgical Processing: Used in ore flotation and as a sulfidizing agent in the extraction and refining of certain metals.
• Analytical Chemistry: Employed as a laboratory reagent for qualitative and quantitative analysis requiring sulfide ions.
• Precipitating Agent: Utilized in wastewater treatment and chemical processes to precipitate heavy metal ions as insoluble sulfides.
• Research & Development: Serves as a starting material in material science and inorganic chemistry research for developing novel compounds.
• Leather Processing: Historically used in the depilatory stage of leather tanning, though use has declined with modern alternatives.

Quality Control

Our Barium Hydrosulfide Tetrahydrate is manufactured under controlled conditions to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing specific results for each lot is provided to guarantee the product meets agreed specifications and your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture and decomposition. Keep away from strong acids and oxidizing agents.
