Chemical Structure

4-(Difluoromethyl)-3-fluoropicolinoyl chloride CAS 1804706-79-3 chemical structure

Description

The occurrence of 4-(Difluoromethyl)-3-fluoropicolinoyl chloride is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(Difluoromethyl)-3-fluoropicolinoyl chloride (CAS 1804706-79-3) is a high-purity analytical reference standard with the molecular formula C7H3ClF3NO and a molecular weight of 209.55 g/mol.

4-(Difluoromethyl)-3-fluoropicolinoyl chloride (C7H3ClF3NO) contains an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 4-(Difluoromethyl)-3-fluoropicolinoyl 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.
