Chemical Structure
Description
The occurrence of 3-[3-(tert-Butyl)-6,8-difluoro-[1,2,4]triazolo[4,3-a]pyridin-7-yl]-N-cyclopropyl-5-fluoro-4-methylbenzamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-[3-(tert-Butyl)-6,8-difluoro-[1,2,4]triazolo[4,3-a]pyridin-7-yl]-N-cyclopropyl-5-fluoro-4-methylbenzamide (CAS 1057394-06-5), a certified reference material (molecular formula C21H21F3N4O, MW 402.41 g/mol) for analytical method development and quality control.
3-[3-(tert-Butyl)-6,8-difluoro-[1,2,4]triazolo[4,3-a]pyridin-7-yl]-N-cyclopropyl-5-fluoro-4-methylbenzamide (C21H21F3N4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
