Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methyl-[1,2,4]triazolo[4,3-a]pyrimidine.
CATO supplies 3-Methyl-[1,2,4]triazolo[4,3-a]pyrimidine (CAS 65267-32-5), a certified reference material (molecular formula C6H6N4, MW 134.14 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methyl-[1,2,4]triazolo[4,3-a]pyrimidine (C6H6N4) is characterized by a nitrile group, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 3-Methyl-[1,2,4]triazolo[4,3-a]pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
