Description
Compared with other compounds in its class, the molecular weight of 160.12 g/mol gives 3,5-Difluoro-4-methoxypyridin-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,5-Difluoro-4-methoxypyridin-2-amine (CAS 2738982-46-0), a certified reference material (molecular formula C6H6F2N2O, MW 160.12 g/mol) for analytical method development and quality control.
3,5-Difluoro-4-methoxypyridin-2-amine (C6H6F2N2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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), 3,5-Difluoro-4-methoxypyridin-2-amine 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.
