Chemical Structure

4-Bromo-6-cyano-5-(difluoromethyl)picolinoyl chloride CAS 1805232-30-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-6-cyano-5-(difluoromethyl)picolinoyl chloride.

4-Bromo-6-cyano-5-(difluoromethyl)picolinoyl chloride (CAS 1805232-30-7) is a high-purity analytical reference standard with the molecular formula C8H2BrClF2N2O and a molecular weight of 295.47 g/mol.

4-Bromo-6-cyano-5-(difluoromethyl)picolinoyl chloride (C8H2BrClF2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. 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-Bromo-6-cyano-5-(difluoromethyl)picolinoyl 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.
