2,3,4,5,6-Pentafluorophenyl 4-{[(4-methoxyphenyl)methyl]amino}-1-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate CAS 866136-92-7

Description

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.

CATO supplies 2,3,4,5,6-Pentafluorophenyl 4-{[(4-methoxyphenyl)methyl]amino}-1-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate (CAS 866136-92-7), a certified reference material (molecular formula C22H15F5N4O3, MW 478.37 g/mol) for analytical method development and quality control.

2,3,4,5,6-Pentafluorophenyl 4-{[(4-methoxyphenyl)methyl]amino}-1-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate (C22H15F5N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
