3-Pyridinecarboxylic acid, 2-chloro-6-(trifluoromethoxy)- CAS 1221172-04-8 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 3-Pyridinecarboxylic acid, 2-chloro-6-(trifluoromethoxy)-.

CATO supplies 3-Pyridinecarboxylic acid, 2-chloro-6-(trifluoromethoxy)- (CAS 1221172-04-8), a certified reference material (molecular formula C7H3ClF3NO3, MW 241.55 g/mol) for analytical method development and quality control.

3-Pyridinecarboxylic acid, 2-chloro-6-(trifluoromethoxy)- (C7H3ClF3NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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 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.

As a certified reference material (CRM), 3-Pyridinecarboxylic acid, 2-chloro-6-(trifluoromethoxy)- 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.
