4-(4-Methoxyphenyl)-3-methyl-6-oxo-1-(1,4,5,6-tetrahydropyrimidin-2-yl)-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-b]pyridine-5-carbonitrile CAS 478043-74-2

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 4-(4-Methoxyphenyl)-3-methyl-6-oxo-1-(1,4,5,6-tetrahydropyrimidin-2-yl)-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-b]pyridine-5-carbonitrile (CAS 478043-74-2), a certified reference material (molecular formula C19H20N6O2, MW 364.40 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(4-Methoxyphenyl)-3-methyl-6-oxo-1-(1,4,5,6-tetrahydropyrimidin-2-yl)-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-b]pyridine-5-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 364.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
