Chemical Structure

3,4-Dichloro-5-fluorobenzoyl chloride CAS 1806353-92-3 chemical structure

Description

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.

3,4-Dichloro-5-fluorobenzoyl chloride (CAS 1806353-92-3) is a high-purity analytical reference standard with the molecular formula C7H2Cl3FO and a molecular weight of 227.45 g/mol.

The molecular framework of 3,4-Dichloro-5-fluorobenzoyl chloride (C7H2Cl3FO) is characterized by a hydroxyl group, an ether linkage, fluorine/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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 3,4-Dichloro-5-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.
