Chemical Structure

3,4-dimethyl-4,5-dihydro-1H-1,2,4-triazol-5-one CAS 54770-19-3 chemical structure

Description

The molecular framework of 3,4-dimethyl-4,5-dihydro-1H-1,2,4-triazol-5-one (C4H7N3O) is characterized by an amide group, a hydroxyl group, an ether linkage. 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.

CATO supplies 3,4-dimethyl-4,5-dihydro-1H-1,2,4-triazol-5-one (CAS 54770-19-3), a certified reference material (molecular formula C4H7N3O, MW 113.12 g/mol) for analytical method development and quality control.

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 3,4-dimethyl-4,5-dihydro-1H-1,2,4-triazol-5-one 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.
