Chemical Structure
Description
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (2-Chlorophenyl)methylphosphonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(2-Chlorophenyl)methylphosphonic acid (CAS 13249-95-1), molecular formula C7H8ClO3P and molecular weight 206.56 g/mol, is a CATO reference standard with documented purity and traceability.
