Chemical Structure
Description
5-Ethyl-6-(4-ethylphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (CAS 922736-84-3), molecular formula C15H17N5 and molecular weight 267.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Ethyl-6-(4-ethylphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (C15H17N5) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Ethyl-6-(4-ethylphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine 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.
