CATO supplies 3,3-[[[3-[(1E)-2-(7-Chloro-2-quinolinyl)ethenyl]phenyl]methylene]bis(thio)]bis-propanoic Acid 1,1-Dimethyl Ester (CAS 120385-96-8), a certified reference material (molecular formula C26H26ClNO4S2, MW 516.07 g/mol) for analytical method development and quality control.
The molecular framework of 3,3-[[[3-[(1E)-2-(7-Chloro-2-quinolinyl)ethenyl]phenyl]methylene]bis(thio)]bis-propanoic Acid 1,1-Dimethyl Ester (C26H26ClNO4S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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).
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.
