7-(Chlorodifluoromethyl)-5-methyl-3-(pyridin-2-yl)pyrazolo[1,5-a]pyrimidine CAS 866049-87-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(Chlorodifluoromethyl)-5-methyl-3-(pyridin-2-yl)pyrazolo[1,5-a]pyrimidine.

CATO supplies 7-(Chlorodifluoromethyl)-5-methyl-3-(pyridin-2-yl)pyrazolo[1,5-a]pyrimidine (CAS 866049-87-8), a certified reference material (molecular formula C13H9ClF2N4, MW 294.69 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 7-(Chlorodifluoromethyl)-5-methyl-3-(pyridin-2-yl)pyrazolo[1,5-a]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
