Chemical Structure
Description
CATO supplies 7-chloro-3-methyl-[1,2,4]triazolo[4,3-c]pyrimidine (CAS 1094292-91-7), a certified reference material (molecular formula C6H13ClN4, MW 176.65 g/mol) for analytical method development and quality control.
Structurally, 7-chloro-3-methyl-[1,2,4]triazolo[4,3-c]pyrimidine (C6H13ClN4) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 176.65 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
