Compared with other compounds in its class, the molecular weight of 249.28 g/mol gives 2-(Methylthio)-5-(trifluoromethyl)benzo[d]thiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(Methylthio)-5-(trifluoromethyl)benzo[d]thiazole (CAS 77205-93-7), a certified reference material (molecular formula C9H6F3NS2, MW 249.28 g/mol) for analytical method development and quality control.
The molecular framework of 2-(Methylthio)-5-(trifluoromethyl)benzo[d]thiazole (C9H6F3NS2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine 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.
