Chemical Structure
Description
CATO supplies 2-Chloro-4-(methylthio)-1,3,5-triazine (CAS 61810-07-9), a certified reference material (molecular formula C4H4ClN3S, MW 161.61 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-4-(methylthio)-1,3,5-triazine (C4H4ClN3S) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
