Description
CATO manufactures 4-Chloro-3-ethoxy-2-fluorobenzoyl chloride 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.
CATO supplies 4-Chloro-3-ethoxy-2-fluorobenzoyl chloride (CAS 1323966-42-2), a certified reference material (molecular formula C9H7Cl2FO2, MW 237.06 g/mol) for analytical method development and quality control.
4-Chloro-3-ethoxy-2-fluorobenzoyl chloride (C9H7Cl2FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
