Chloromaleic Acid Anhydride (CAS 96-02-6) is a high-purity analytical reference standard with the molecular formula C4HClO3 and a molecular weight of 132.50 g/mol.
The molecular framework of Chloromaleic Acid Anhydride (C4HClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
