Chemical Structure
Description
CATO supplies 1-(5-(((2-Cyanoethyl)thio)methyl)thiazol-2-yl)guanidine (CAS 131184-89-9), a certified reference material (molecular formula C8H11N5S2, MW 241.34 g/mol) for analytical method development and quality control.
The molecular framework of 1-(5-(((2-Cyanoethyl)thio)methyl)thiazol-2-yl)guanidine (C8H11N5S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.
