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 N-Ethyl-1H-1,2,4-triazol-5-amine.
CATO supplies N-Ethyl-1H-1,2,4-triazol-5-amine (CAS 89279-89-0), a certified reference material (molecular formula C4H8N4, MW 112.13 g/mol) for analytical method development and quality control.
The molecular framework of N-Ethyl-1H-1,2,4-triazol-5-amine (C4H8N4) is characterized by 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).
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 N-Ethyl-1H-1,2,4-triazol-5-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.
