(1S)\u200b-\u200b2-\u200bChloro-\u200b1-\u200b(2,\u200b4-\u200bdichlorophenyl)\u200bethanol(CAS: 126534-31-4)

(1S)-2-Chloro-1-(2,4-dichlorophenyl)ethanol is a crystalline compound with a molecular weight of approximately 274.03 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is stable under acidic and basic conditions but can react with nucleophiles at the chlorine substituents. It is often used as a precursor in organic synthesis and pharmaceuticals.

(1S)-2-Chloro-1-(2,4-dichlorophenyl)ethanol is usually synthesized via the coupling of 2,4-dichlorophenyl chloromethyl ether with chloroethanol in the presence of a base such as sodium hydride. The reaction is carried out under anhydrous conditions to ensure high yield and selectivity. The product is then isolated and purified through crystallization or other separation techniques.

(1S)-2-Chloro-1-(2,4-dichlorophenyl)ethanol is used in various industries, particularly in the pharmaceutical sector for the synthesis of drugs. It is also utilized in the production of certain polymers, where it acts as a monomer or intermediate. Additionally, it can be found in the development of chemical sensors and as a component in semiconductor manufacturing processes.

When handling (1S)-2-Chloro-1-(2,4-dichlorophenyl)ethanol, it is important to use personal protective equipment (PPE) such as gloves and safety goggles. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Proper storage should be in a cool, dry place away from direct sunlight. Spills should be cleaned up immediately with appropriate absorbents, and the material safety data sheet (MSDS) should be consulted for detailed emergency procedures.
