CATO supplies 7-Hydrazinyl-5-methyl-3-phenylpyrazolo[1,5-a]pyrimidine (CAS 58347-29-8), a certified reference material (molecular formula C13H13N5, MW 239.28 g/mol) for analytical method development and quality control.
The molecular framework of 7-Hydrazinyl-5-methyl-3-phenylpyrazolo[1,5-a]pyrimidine (C13H13N5) 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.
