Description

Compared with other compounds in its class, the molecular weight of 187.14 g/mol gives 2-(Difluoromethyl)-3-hydroxy-4-methylpyridine-6-carboxaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(Difluoromethyl)-3-hydroxy-4-methylpyridine-6-carboxaldehyde (CAS 1805487-22-2) is a high-purity analytical reference standard with the molecular formula C8H7F2NO2 and a molecular weight of 187.14 g/mol.

2-(Difluoromethyl)-3-hydroxy-4-methylpyridine-6-carboxaldehyde (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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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)-3-hydroxy-4-methylpyridine-6-carboxaldehyde 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.
