6-Phenyl-1,2,4-triazine-3,5(2H,4H)-dione CAS 23891-08-9

Description

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.

CATO supplies 6-Phenyl-1,2,4-triazine-3,5(2H,4H)-dione (CAS 23891-08-9), a certified reference material (molecular formula C7H4Cl2F3NO2S, MW 294.08 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H4Cl2F3NO2S, 6-Phenyl-1,2,4-triazine-3,5(2H,4H)-dione contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 294.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
