3-Fluorobenzyl Chloride CAS 456-42-8

1. 3-Fluorobenzyl chloride is widely utilized as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-cancer and anti-inflammatory drugs, where the fluorine atom enhances drug efficacy .
2. 3-Fluorobenzyl chloride CAS 456-42-8 serves as a versatile building block in organic synthesis for creating complex molecules via nucleophilic substitution reactions, enabling the exploration of new chemical reactions and the development of innovative materials .
3. Applications of 3-Fluorobenzyl chloride also include its use in polymer chemistry to modify polymer properties, leading to specialized materials with improved thermal and mechanical characteristics, and in agrochemical development for synthesizing pesticides and herbicides .

1. Store 3-Fluorobenzyl chloride in a tightly sealed container under an inert gas (e.g., argon filling) in a cool, dry, and well-ventilated place away from heat, sparks, and open flames; recommended storage is in a cool, dark place (<15°C) or at room temperature, protected from moisture .
2. Keep 3-Fluorobenzyl chloride strictly away from strong oxidizing agents, bases, alcohols, amines, and steel, as it is incompatible with these materials and can react violently .
3. Always use 3-Fluorobenzyl chloride CAS 456-42-8 appropriate personal protective equipment (PPE) including chemical-resistant gloves, tightly fitting safety goggles and/or face shield, and protective clothing; use only with explosion-proof equipment and adequate ventilation, and avoid breathing vapors, mist, or gas .

1. Immediately isolate the spill area, eliminate all ignition sources, and ensure adequate ventilation; contain 3-Fluorobenzyl chloride using inert, non-combustible absorbent material (e.g., dry sand) and absolutely avoid contact with water .
2. Carefully collect 3-Fluorobenzyl chloride CAS 456-42-8 using spark-proof tools and place it into a sealed, labeled corrosion-resistant chemical waste container 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; 3-Fluorobenzyl chloride is classified for transport (UN2920, Hazard Class 8 (3), PG II) and requires hazardous waste disposal .

1. 3-Fluorobenzyl chloride is classified as a flammable liquid and vapor (H226) that is corrosive, causing severe skin burns and serious eye damage (H314/H318). 3-Fluorobenzyl chloride CAS 456-42-8 is a known lachrymator (tear gas agent) and inhalation may cause corrosive injuries to the upper respiratory tract and lungs .
2. 3-Fluorobenzyl chloride is harmful if swallowed, inhaled, or absorbed through the skin; thermal decomposition or combustion produces toxic and corrosive fumes including carbon monoxide, hydrogen chloride, and hydrogen fluoride . The flash point is 58 °C (138 °F) .
3. Always consult 3-Fluorobenzyl chloride CAS 456-42-8 the specific Safety Data Sheet (SDS) for 3-Fluorobenzyl chloride for complete hazard information, first-aid procedures (P303+P361+P353 for skin, P305+P351+P338 for eyes, P301+P330+P331 for ingestion), and handling instructions. Precautionary statements include P210 (keep away from heat/sparks/open flames), P280 (wear protective gloves/eye protection), and P310 (immediately call a poison center/doctor) .
