Disulfurous acid, potassium salt (1:2)(CAS: 16731-55-8)

Disulfurous acid, potassium salt (1:2) is a chemical compound with the CAS number 16731-55-8. It is the potassium salt of hydrogen sulfide (H2S), with the chemical formula KHS. This compound is a strong reducing agent, water-soluble, and commonly used in chemical synthesis. It is also known as potassium hydrosulfide and exhibits acidic properties in aqueous solutions.

Disulfurous acid, potassium salt (CAS: 16731-55-8) is primarily used in pharmaceuticals for synthesizing sulfur-containing compounds, in industrial processes for producing hydrogen sulfide gas, and in research applications. It may also serve as a reagent in organic chemistry and be utilized in the manufacture of certain dyes or pesticides. Its utility stems from its ability to release H2S under controlled conditions.

Disulfurous acid, potassium salt (CAS: 16731-55-8) requires careful handling due to its potential toxicity. Inhalation or contact with skin and eyes can cause irritation, and it may release harmful hydrogen sulfide gas. Safety measures include using protective gloves, goggles, and ventilation. It is classified as a hazardous material under OSHA standards, necessitating proper storage and disposal protocols.

Disulfurous acid, potassium salt (CAS: 16731-55-8) should be stored in airtight, moisture-proof containers in a cool, dry, and dark environment. It is hygroscopic and may degrade if exposed to humidity or light. Storage conditions should maintain temperatures below 25°C to ensure stability, and it must be kept away from incompatible substances like oxidizers to prevent chemical reactions.
