(4-AMino-6-methyl-1-phenyl-1h-pyrazolo[3,4-b]pyridin-5-yl)(phenyl)methanone CAS 2089391-67-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-AMino-6-methyl-1-phenyl-1h-pyrazolo[3,4-b]pyridin-5-yl)(phenyl)methanone.

CATO supplies (4-AMino-6-methyl-1-phenyl-1h-pyrazolo[3,4-b]pyridin-5-yl)(phenyl)methanone (CAS 2089391-67-1), a certified reference material (molecular formula C20H16N4O, MW 328.37 g/mol) for analytical method development and quality control.

Structurally, (4-AMino-6-methyl-1-phenyl-1h-pyrazolo[3,4-b]pyridin-5-yl)(phenyl)methanone (C20H16N4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 328.37 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
