TCI C1212 4-(Chloromethyl)benzoic Acid, CAS 1642-81-5, is a bifunctional aromatic building block carrying a reactive benzylic chloride and a carboxylic acid in a para relationship. The chloromethyl group alkylates amines, thiols, and oxygen nucleophiles, while the acid group can be activated for amide or ester formation, making the compound a convenient rigid linker. It is commonly applied to resin and surface functionalisation for solid-phase synthesis, as well as to conjugate and polymer preparation. AMI Scientific supplies a 25 g pack for research use; benzyl chloride derivatives are strong irritants, so weigh and transfer the material in a fume hood following the manufacturer's Safety Data Sheet.
