3-Chlorobenzyl chloride CAS 620-20-2
Pharmaceutical Materials 2025-03-03
3-Chlorobenzyl chloride, also known as m-chlorobenzyl chloride, is a key intermediate in organic synthesis with the molecular formula C₇H₆Cl₂ and a molecular weight of 161.03 g/mol. It is widely utilized in pharmaceuticals, agrochemicals, and specialty chemicals for the production of intermediates such as β-blockers, pesticides, and dyes. The compound is a colorless to pale yellow liquid with a boiling point of 215–216 °C and a density of 1.27 g/cm³. Its reactivity stems from the chloromethyl group, enabling nucleophilic substitution and coupling reactions. However, it poses hazards due to its corrosive nature (GHS Category 1B) and ability to cause severe skin and eye damage. Proper handling under inert gas and strict adherence to safety protocols (e.g., wearing PPE) are essential to mitigate risks associated with its use.
