5-Phenoxy-2-phenyl-6-(1H-1,2,4-triazol-3-yl)-2,3-dihydropyridazin-3-one CAS 338405-34-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Phenoxy-2-phenyl-6-(1H-1,2,4-triazol-3-yl)-2,3-dihydropyridazin-3-one.

5-Phenoxy-2-phenyl-6-(1H-1,2,4-triazol-3-yl)-2,3-dihydropyridazin-3-one (CAS 338405-34-8), molecular formula C18H13N5O2 and molecular weight 331.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Phenoxy-2-phenyl-6-(1H-1,2,4-triazol-3-yl)-2,3-dihydropyridazin-3-one (C18H13N5O2) is characterized by a steroid 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 5-Phenoxy-2-phenyl-6-(1H-1,2,4-triazol-3-yl)-2,3-dihydropyridazin-3-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.
