4-Bromo-2-(difluoromethyl)-5-fluoro-3-methylpyridine CAS 1806829-28-6

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-2-(difluoromethyl)-5-fluoro-3-methylpyridine.

4-Bromo-2-(difluoromethyl)-5-fluoro-3-methylpyridine (CAS 1806829-28-6), molecular formula C7H5BrF3N and molecular weight 240.02 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, 4-Bromo-2-(difluoromethyl)-5-fluoro-3-methylpyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 4-Bromo-2-(difluoromethyl)-5-fluoro-3-methylpyridine 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.
