Ethyl 3-(4-methyl-3,5-dioxo-2-phenyl-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)-1,2,4-oxadiazole-5-carboxylate CAS 933194-25-3 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 Ethyl 3-(4-methyl-3,5-dioxo-2-phenyl-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)-1,2,4-oxadiazole-5-carboxylate.

Ethyl 3-(4-methyl-3,5-dioxo-2-phenyl-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)-1,2,4-oxadiazole-5-carboxylate (CAS 933194-25-3) is a high-purity analytical reference standard with the molecular formula C15H13N5O5 and a molecular weight of 343.29 g/mol.

The molecular framework of Ethyl 3-(4-methyl-3,5-dioxo-2-phenyl-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)-1,2,4-oxadiazole-5-carboxylate (C15H13N5O5) is characterized by a flavonoid core, 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. 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 Ethyl 3-(4-methyl-3,5-dioxo-2-phenyl-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)-1,2,4-oxadiazole-5-carboxylate 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.
