Sodium Hydrosulfide (NaHS)

Product Description:

Sodium hydrosulfide (NaHS) is a versatile inorganic chemical raw material available in the form of white or slightly light yellow amorphous crystals or powder. This corrosive substance is easily soluble in water, producing a strongly alkaline aqueous solution. Widely utilized in industries such as dyes, pharmaceuticals, leather, textiles, papermaking, and more, sodium hydrosulfide is a crucial component in various manufacturing processes. Additionally, it serves as a common chemical reagent for applications in analytical chemistry and organic synthesis.

• Wear protective equipment: Always wear chemical protective glasses, gloves, and clothing to prevent skin and eye contact.


• Storage and ventilation: Store sodium hydrosulfide in a dry, cool, and ventilated area to avoid contact with oxidants and combustibles. Ensure proper ventilation to prevent toxic gas accumulation.


• Avoid contact with other substances: Sodium hydrosulfide is a strong reducing agent, so avoid contact with acids, oxidants, and flammable materials.


• Avoid inhalation and swallowing: The gas released by sodium hydrosulfide is irritating and toxic. Take precautions to avoid inhalation and swallowing.


• Waste disposal: Properly dispose of sodium hydrosulfide waste by neutralizing it into a neutral solution before disposal.


• Prevent splashing and dusting: Be cautious to prevent splashing and dusting when handling sodium hydrosulfide. Rinse immediately with water if splashing occurs.
