2-Cyano-3-(difluoromethyl)-4-methylbenzoic acid CAS 1807299-19-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Cyano-3-(difluoromethyl)-4-methylbenzoic acid.

2-Cyano-3-(difluoromethyl)-4-methylbenzoic acid (CAS 1807299-19-9), molecular formula C10H7F2NO2 and molecular weight 211.16 g/mol, is a CATO reference standard with documented purity and traceability.

2-Cyano-3-(difluoromethyl)-4-methylbenzoic acid (C10H7F2NO2) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, 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-Cyano-3-(difluoromethyl)-4-methylbenzoic 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.
