Chemical Structure

1,3,4-Triphenyl-1H-1,2,4-triazole-5(4H)-selenone CAS 185761-76-6 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 1,3,4-Triphenyl-1H-1,2,4-triazole-5(4H)-selenone.

1,3,4-Triphenyl-1H-1,2,4-triazole-5(4H)-selenone (CAS 185761-76-6) is a high-purity analytical reference standard with the molecular formula C20H15N3Se and a molecular weight of 376.31 g/mol.

1,3,4-Triphenyl-1H-1,2,4-triazole-5(4H)-selenone (C20H15N3Se) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
