Cas no 16721-80-5 (sodium hydrosulfide)
Sodium hydrosulfide (NaHS) is an inorganic compound commonly available as a solution or solid. It serves as a versatile reducing agent and sulfur source in industrial applications, including pulp and paper processing, leather tanning, and mining (particularly in copper ore flotation). NaHS is valued for its high reactivity and solubility in water, facilitating precise sulfur transfer in chemical synthesis. It also acts as a scavenger for heavy metals in wastewater treatment. Handling requires caution due to its corrosive nature and potential release of toxic hydrogen sulfide gas. Proper storage in airtight containers and adherence to safety protocols are essential for safe usage.
