Chemical Structure

2-Cyclopropylmalonoyl dichloride CAS 743478-64-0 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Cyclopropylmalonoyl dichloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 181.02 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.
