Application
1. 1,4-Difluorobenzene is a critical building block in synthesizing active pharmaceutical ingredients and fluorinated intermediates for drug development .
2. 1 4-Difluorobenzene CAS 540-36-3 is used to produce specialty polymers with high thermal stability for automotive and electronic applications and to develop high-performance organic semiconductors .
3. 1,4-Difluorobenzene serves as an analytical standard in environmental testing (e.g., for GC-MS methods) and as a solvent in various analytical techniques .
Storage and Precautions
1. Store 1,4-Difluorobenzene in a tightly sealed container in a cool, dry, well-ventilated area, away from heat, sparks, and open flames; a flammable materials area or refrigeration at 2-8°C is recommended .
2. Keep 1 4-Difluorobenzene CAS 540-36-3 strictly separated from strong oxidizing agents, as 1,4-Difluorobenzene is incompatible, and ensure containers are grounded to prevent electrostatic discharge .
3. Handle 1,4-Difluorobenzene using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and in a fume hood to avoid breathing vapors .
Emergency response to leakage
1. Isolate the spill 1 4-Difluorobenzene CAS 540-36-3 area, eliminate all ignition sources, and contain liquid 1,4-Difluorobenzene using dry inert absorbent material like sand, preventing entry into drains or waterways .
2. Collect absorbed 1,4-Difluorobenzene using non-sparking tools into sealed, labeled containers for disposal according to hazardous material regulations .
3. Personnel cleaning 1,4-Difluorobenzene spills must wear full protective equipment including self-contained breathing apparatus and ensure adequate ventilation during cleanup .
Safety Information
1. 1,4-Difluorobenzene is an extremely flammable liquid and vapor (H224) with a flash point of 2°C, and overexposure may cause dizziness, nausea, narcosis, and respiratory failure .
2. 1 4-Difluorobenzene CAS 540-36-3 is harmful if swallowed (H302), toxic if absorbed through skin (H311), and harmful if inhaled (H332); combustion produces toxic fumes including carbon oxides and hydrogen fluoride .
3. 1,4-Difluorobenzene is classified for transport as a flammable liquid (UN 1993, Hazard Class 3, Packing Group II) and requires handling with precautionary statements P210, P233, P240, and P280 .
