Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 198.60 g/mol gives 3-(Chlorocarbonyl)phenyl Acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Chlorocarbonyl)phenyl Acetate (CAS 16446-73-4), molecular formula C9H7ClO3 and molecular weight 198.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(Chlorocarbonyl)phenyl Acetate (C9H7ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
CATO manufactures 3-(Chlorocarbonyl)phenyl Acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
