N-(5-Methylpyridin-2-yl)pyrazolo[1,5-a]pyrimidine-2-carboxamide CAS 678984-00-4

Description

The molecular framework of N-(5-Methylpyridin-2-yl)pyrazolo[1,5-a]pyrimidine-2-carboxamide (C13H11N5O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).

N-(5-Methylpyridin-2-yl)pyrazolo[1,5-a]pyrimidine-2-carboxamide (CAS 678984-00-4), molecular formula C13H11N5O and molecular weight 253.26 g/mol, is a CATO reference standard with documented purity and traceability.

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.
