Chemical Structure
Description
The molecular framework of 4-Amino-6-(3-chlorophenyl)-1,6-dihydro-1,3,5-triazine-2-thiol (C9H9ClN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 4-Amino-6-(3-chlorophenyl)-1,6-dihydro-1,3,5-triazine-2-thiol (CAS 931799-35-8), a certified reference material (molecular formula C9H9ClN4S, MW 240.71 g/mol) for analytical method development and quality control.
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.
