4-Chlorophenol CAS 106-48-9

1. 4-Chlorophenol is a critical chemical intermediate for producing fungicides, herbicides (e.g., in pesticide synthesis), and pharmaceuticals like aspirin .
2. 4-Chlorophenol CAS 106-48-9 is utilized as a key building block in the dye industry for manufacturing dark, long-lasting dyes and as a selective solvent in mineral oil refining .
3. 4-Chlorophenol serves as a model substrate in environmental research for studying the biodegradation of xenobiotic compounds and evaluating advanced wastewater treatment processes .

1. Store 4-Chlorophenol in a tightly sealed container in a cool, dry, well-ventilated area, away from heat sources and direct sunlight .
2. Keep 4-Chlorophenol CAS 106-48-9 strictly separated from strong oxidizing agents, acids, acid anhydrides, and foodstuffs to prevent hazardous reactions .
3. Handle 4-Chlorophenol using appropriate personal protective equipment including nitrile rubber gloves and tightly fitting safety goggles, as 4-Chlorophenol is corrosive and causes severe skin and eye damage .

1. Isolate the spill area, ensure adequate ventilation, and wear full protective equipment including a self-contained breathing apparatus before handling 4-Chlorophenol .
2. Contain solid 4-Chlorophenol CAS 106-48-9 by sweeping into sealed, labeled containers for disposal using spark-proof tools and avoiding dust generation; for small spills, use dry inert absorbent material .
3. Prevent 4-Chlorophenol from entering drains or waterways, as 4-Chlorophenol is toxic to aquatic life with long-lasting effects, and dispose of waste through a licensed hazardous waste facility (UN2020, Hazard Class 6.1) .

1. 4-Chlorophenol is classified with GHS signal word "Danger" and is harmful if swallowed (oral LD50: 670 mg/kg rat), in contact with skin, or if inhaled (LC50: 1010 mg/m³ rat/4h) .
2. 4-Chlorophenol CAS 106-48-9 causes severe skin burns and serious eye damage (H314, H318) and may cause damage to organs through prolonged or repeated exposure .
3. 4-Chlorophenol has a flash point of 121°C, is combustible and forms explosive dust-air mixtures on intense heating; thermal decomposition produces toxic fumes including carbon oxides and hydrogen chloride gas .
