3-Bromophenol CAS 591-20-8

1. 3-Bromophenol CAS 591-20-8 is widely used as an important intermediate in the synthesis of pharmaceuticals, agrochemicals, dyestuffs, and specialty polymers, where 3-Bromophenol contributes to materials with improved thermal and mechanical properties .
2. The compound acts as an enzyme inhibitor in biochemical research and serves as a fluorometric probe in wastewater treatment and as a tracer for studying metabolic pathways, such as in the proximal tubules of the kidney .
3. Applications of 3-Bromophenol also include its use in analytical chemistry as a reagent for detecting other substances, in the preparation of 3-bromophenyl esters , and in environmental monitoring for developing pollutant sensors .

1. Store 3-Bromophenol CAS 591-20-8 in a tightly sealed container under an inert gas (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place, protected from light, as 3-Bromophenol is light and air sensitive . Recommended storage temperatures range from 2-8 °C (refrigerated) to a cool, dark place below 15°C .
2. Keep 3-Bromophenol strictly away from strong oxidizing agents, acid anhydrides, and acid chlorides to prevent hazardous reactions .
3. Always use appropriate personal protective equipment (PPE) including nitrile rubber gloves, tightly fitting safety goggles, face protection, and impervious clothing; use only with adequate ventilation (fume hood) and avoid breathing dust, vapors, mist, or gas .

1. Immediately isolate the spill area, eliminate all ignition sources, and avoid dust generation; contain 3-Bromophenol CAS 591-20-8 using inert, non-combustible absorbent material and do NOT let it enter drains or waterways as it is an environmental hazard .
2. Carefully sweep 3-Bromophenol up or shovel the spilled 3-Bromophenol solid using non-sparking tools, and place the collected material into sealed, labeled chemical waste containers for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear suitable PPE including self-contained breathing apparatus (SCBA) during cleanup ; for fire, use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide extinguishing media . 3-Bromophenol is classified with UN number 2811 or 1325, Hazard Class 6.1 or 4.1, PG II/III .

1. 3-Bromophenol CAS 591-20-8 is classified with GHS signal word "Warning" as it is harmful if swallowed (H302), in contact with skin (H312), or if inhaled (H332). It causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) . Acute oral LD50 is approximately 1540 mg/kg in rats .
2. 3-Bromophenol is combustible with a flash point >110°C and may form explosive mixtures with air as a powder . Thermal decomposition or combustion produces toxic and irritating fumes including carbon monoxide, carbon dioxide, and hydrogen bromide gas .
3. Always consult 3-Bromophenol the specific Safety Data Sheet (SDS) for 3-Bromophenol for complete hazard information, first-aid procedures, and handling instructions; precautionary statements include P261 (avoid breathing dust), P280 (wear protective gloves/eye protection), and P273 (avoid release to environment) .
