CATO supplies (E)-{2-[(4-chlorophenyl)sulfanyl]-1-{6-methyl-[1,2,4]triazolo[3,2-b][1,3]thiazol-5-yl}ethylidene}[(4-methylphenyl)methoxy]amine (CAS 866131-18-2), a certified reference material (molecular formula C21H19ClN4OS2, MW 442.98 g/mol) for analytical method development and quality control.
(E)-{2-[(4-chlorophenyl)sulfanyl]-1-{6-methyl-[1,2,4]triazolo[3,2-b][1,3]thiazol-5-yl}ethylidene}[(4-methylphenyl)methoxy]amine (C21H19ClN4OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
