2-(7-(p-Tolyl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidin-3-yl)phenol CAS 901270-98-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(7-(p-Tolyl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidin-3-yl)phenol.

CATO supplies 2-(7-(p-Tolyl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidin-3-yl)phenol (CAS 901270-98-2), a certified reference material (molecular formula C19H14N6O, MW 342.35 g/mol) for analytical method development and quality control.

Structurally, 2-(7-(p-Tolyl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidin-3-yl)phenol (C19H14N6O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 342.35 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.
