Chemical Structure
Description
The occurrence of Fenchlorphos-Oxon is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Fenchlorphos-Oxon (CAS 3983-45-7), molecular formula C8H8Cl3O4P and molecular weight 305.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Fenchlorphos-Oxon (C8H8Cl3O4P) is characterized by a phosphate ester group, 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.
CATO manufactures Fenchlorphos-Oxon 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.
