Sodium Hydrosulfide (NaHS)

CAS No.: 16721-80-5 | HS Code: 28309090

Sodium Hydrosulfide (NaHS), also known as sodium hydrogen sulfide, is a widely applied inorganic sulfur compound with strong reducibility and excellent water solubility. Our factory supplies high-quality industrial-grade sodium hydrosulfide in yellow flakes, stable in composition, low in impurities, and consistent batch quality for global industrial buyers. As a reliable source of sulfide ions, it serves as a core raw material and processing auxiliary across multiple industries.

Product Properties

Sodium hydrosulfide is yellow to light yellow flaky solid, hygroscopic, easily soluble in water. It has a characteristic rotten-egg odor. It reacts with acid to release hydrogen sulfide gas. Our product is strictly controlled for impurity content, avoiding unstable performance during your production process.

Main Applications
