CATO supplies 4H,5H,6H,7H-[1,2,4]Triazolo-[1,5-a]pyrimidine hydrochloride (CAS 1208673-90-8), a certified reference material (molecular formula C5H8N4HCl, MW 160.60 g/mol) for analytical method development and quality control.
Structurally, 4H,5H,6H,7H-[1,2,4]Triazolo-[1,5-a]pyrimidine hydrochloride (C5H8N4HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 160.60 g/mol, it falls into the medium-molecular-weight range. 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.
