Chemical Structure

2,3-Dichloro-4-(difluoromethyl)pyridine-5-acetic acid CAS 1806005-18-4 chemical structure

Description

As a certified reference material (CRM), 2,3-Dichloro-4-(difluoromethyl)pyridine-5-acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

2,3-Dichloro-4-(difluoromethyl)pyridine-5-acetic acid (CAS 1806005-18-4) is a high-purity analytical reference standard with the molecular formula C8H5Cl2F2NO2 and a molecular weight of 256.03 g/mol.

The molecular framework of 2,3-Dichloro-4-(difluoromethyl)pyridine-5-acetic acid (C8H5Cl2F2NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. 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.
