CATO supplies 5-Methyl-N-(pyridin-4-yl)-3-(p-tolyl)pyrazolo[1,5-a]pyrimidin-7-amine (CAS 902035-75-0), a certified reference material (molecular formula C19H17N5, MW 315.37 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methyl-N-(pyridin-4-yl)-3-(p-tolyl)pyrazolo[1,5-a]pyrimidin-7-amine (C19H17N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
