Chemical Structure
Description
The molecular framework of 1h-imidazole,4-(methylthio)-(9ci) 4-(Methylthio)-1H-imidazole 4-(methylthio)imidazole, 97% 5-(methylthio)-1h-imidazole 83553-60-0 (C4H6N2S) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 1h-imidazole,4-(methylthio)-(9ci) 4-(Methylthio)-1H-imidazole 4-(methylthio)imidazole, 97% 5-(methylthio)-1h-imidazole 83553-60-0 (CAS 83553-60-0), a certified reference material (molecular formula C4H6N2S, MW 114.17 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
