FAQ

What is Potassium Bromide (CAS: 7758-02-3)?

Potassium bromide is an inorganic salt with the chemical formula KBr. It appears as a white, crystalline solid, is odorless, and is highly soluble in water. Known for its stability and hygroscopic nature, it has a melting point of 737°C and a density of 2.73 g/cm³. Commonly used in various industries, it is also recognized by its CAS number 7758-02-3.

What are the main uses of Potassium Bromide (CAS: 7758-02-3)?

Potassium bromide (CAS: 7758-02-3) is widely used in pharmaceuticals as a sedative and anticonvulsant. In industry, it serves as a flame retardant, in chemical synthesis, and in the production of other bromide compounds. It is also employed in photography, as a food additive (e.g., flavoring agent), and in research for analytical purposes. Its versatility makes it a key compound in multiple applications.

Is Potassium Bromide (CAS: 7758-02-3) safe?

Potassium bromide is generally safe when used in recommended concentrations, but it may pose risks if ingested in large amounts or mishandled. It is considered non-toxic in low doses but can cause irritation to skin, eyes, and respiratory systems. Safety guidelines include wearing protective gloves, goggles, and ensuring proper ventilation. Adherence to OSHA standards and handling precautions is essential for safe use.

How should Potassium Bromide (CAS: 7758-02-3) be stored?

Potassium bromide should be stored in airtight, moisture-proof containers in a cool, dry place (ideally below 25°C) to prevent hygroscopic degradation. It is sensitive to humidity and light, so storage in a dark environment is recommended. Keep away from incompatible materials and ensure proper labeling to maintain stability and safety.
