Pyrazole-72 CAS 85833-79-0

Description

Compared with other compounds in its class, the molecular weight of 570.64 g/mol gives Pyrazole-72 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Pyrazole-72 (CAS 85833-79-0), a certified reference material (molecular formula C38H26N4O2, MW 570.64 g/mol) for analytical method development and quality control.

Based on its molecular formula C38H26N4O2, Pyrazole-72 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 570.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
