CATO manufactures 6-Ethyl-7-hydroxy-3-(4-phenyl-4H-1,2,4-triazol-3-yl)-4H-1-benzopyran-4-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.

6-Ethyl-7-hydroxy-3-(4-phenyl-4H-1,2,4-triazol-3-yl)-4H-1-benzopyran-4-one (CAS 847758-37-6), molecular formula C19H15N3O3 and molecular weight 333.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-Ethyl-7-hydroxy-3-(4-phenyl-4H-1,2,4-triazol-3-yl)-4H-1-benzopyran-4-one (C19H15N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 333.34 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.
