2-(Difluoromethyl)pyridine-5-acetic acid CAS 1211540-34-9

Description

Compared with other compounds in its class, the molecular weight of 187.14 g/mol gives 2-(Difluoromethyl)pyridine-5-acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(Difluoromethyl)pyridine-5-acetic acid (CAS 1211540-34-9), molecular formula C8H7F2NO2 and molecular weight 187.14 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Difluoromethyl)pyridine-5-acetic acid (C8H7F2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 2-(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.
