CATO supplies (E)-{[6-(benzylsulfanyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(3,4-dichlorophenyl)methoxy]amine (CAS 338976-37-7), a certified reference material (molecular formula C20H15Cl2N3OS2, MW 448.39 g/mol) for analytical method development and quality control.
(E)-{[6-(benzylsulfanyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(3,4-dichlorophenyl)methoxy]amine (C20H15Cl2N3OS2) 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, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
