Sodium 4-hydroxybenzenesulfonate CAS 825-90-1

1. Sodium 4-hydroxybenzenesulfonate is primarily used as a key intermediate in the synthesis of azo dyes, acid dyes, and fluorescent whitening agents for the textile, paper, and detergent industries.
2. Sodium 4-hydroxybenzenesulfonate CAS 825-90-1 serves as an important monomer or modifier in the production of specialty polymers, including phenol-formaldehyde resins and electroconductive polymers.
3. Sodium 4-hydroxybenzenesulfonate functions as a corrosion inhibitor in industrial water treatment systems and as a stabilizing agent or additive in some photographic and chemical processing solutions.

1. Store sodium 4-hydroxybenzenesulfonate in a cool, dry, well-ventilated area, in tightly sealed containers protected from moisture, heat, and incompatible substances.
2. Keep sodium 4-hydroxybenzenesulfonate CAS 825-90-1 separate from strong oxidizing agents, strong acids, and reactive metals to prevent hazardous decomposition or reactions.
3. Handle sodium 4-hydroxybenzenesulfonate with care to minimize dust generation; ensure containers are clearly labeled and kept closed when not in use.

1. Immediately isolate the spill area and ensure adequate ventilation; carefully contain the spill to prevent sodium 4-hydroxybenzenesulfonate dust from becoming airborne or spreading.
2. Collect spilled sodium 4-hydroxybenzenesulfonate CAS 825-90-1 using a clean, dry tool or a HEPA-filter vacuum cleaner, and place it into a suitable, sealable container for disposal.
3. Clean the contaminated surface thoroughly with plenty of water; collect all contaminated materials (absorbents, wash water) and dispose of them in accordance with local environmental regulations for chemical waste.

1. Sodium 4-hydroxybenzenesulfonate may cause skin irritation, serious eye irritation, and respiratory tract irritation upon exposure to dust or aerosols.
2. Sodium 4-hydroxybenzenesulfonate CAS 825-90-1 can be harmful if swallowed or inhaled in significant quantities, and prolonged or repeated exposure may cause damage to specific organs.
3. Always consult the Safety Data Sheet (SDS) for specific toxicological information and wear appropriate personal protective equipment (PPE), including dust masks, safety goggles, gloves, and protective clothing.
