3-(3-Phenylpyrazolo[1,5-a]pyrimidin-7-yl)aniline CAS 931998-17-3

Description

The occurrence of 3-(3-Phenylpyrazolo[1,5-a]pyrimidin-7-yl)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(3-Phenylpyrazolo[1,5-a]pyrimidin-7-yl)aniline (CAS 931998-17-3), a certified reference material (molecular formula C18H14N4, MW 286.33 g/mol) for analytical method development and quality control.

Structurally, 3-(3-Phenylpyrazolo[1,5-a]pyrimidin-7-yl)aniline (C18H14N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 286.33 g/mol, it falls into the medium-molecular-weight range. 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.

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.
