5-Ethyl-3-(4-fluorophenyl)-[1,2,4]triazolo[4,3-d][1,2,4]triazin-8(7H)-one CAS 1243029-84-6 chemical structure

Description

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.

5-Ethyl-3-(4-fluorophenyl)-[1,2,4]triazolo[4,3-d][1,2,4]triazin-8(7H)-one (CAS 1243029-84-6) is a high-purity analytical reference standard with the molecular formula C12H10FN5O and a molecular weight of 259.24 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 5-Ethyl-3-(4-fluorophenyl)-[1,2,4]triazolo[4,3-d][1,2,4]triazin-8(7H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 259.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 5-Ethyl-3-(4-fluorophenyl)-[1,2,4]triazolo[4,3-d][1,2,4]triazin-8(7H)-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.
