Description
CATO manufactures 3,4-Difluorophenethyl ethyl oxalate 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.
3,4-Difluorophenethyl ethyl oxalate (CAS 1443334-89-1) is a high-purity analytical reference standard with the molecular formula C12H12F2O4 and a molecular weight of 258.22 g/mol.
The molecular framework of 3,4-Difluorophenethyl ethyl oxalate (C12H12F2O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
