2-[(2,4-dimethyl-3,5-dioxo-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)sulfanyl]acetohydrazide CAS 870693-18-8

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.

2-[(2,4-dimethyl-3,5-dioxo-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)sulfanyl]acetohydrazide (CAS 870693-18-8), molecular formula C7H11N5O3S and molecular weight 245.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-[(2,4-dimethyl-3,5-dioxo-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)sulfanyl]acetohydrazide (C7H11N5O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

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.
