Description

Compared with other compounds in its class, the molecular weight of 508.38 g/mol gives 2-((5-(((4-Iodo-2-methylphenyl)amino)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanehydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-((5-(((4-Iodo-2-methylphenyl)amino)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanehydrazide (CAS 1306739-35-4), molecular formula C19H21IN6OS and molecular weight 508.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((5-(((4-Iodo-2-methylphenyl)amino)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanehydrazide (C19H21IN6OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution. 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.

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.
