3,4-Difluoro-5-nitrobenzoyl chloride CAS 1806313-22-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Difluoro-5-nitrobenzoyl chloride.

3,4-Difluoro-5-nitrobenzoyl chloride (CAS 1806313-22-3) is a high-purity analytical reference standard with the molecular formula C7H2ClF2NO3 and a molecular weight of 221.55 g/mol.

The molecular framework of 3,4-Difluoro-5-nitrobenzoyl chloride (C7H2ClF2NO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures 3,4-Difluoro-5-nitrobenzoyl 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.
