Chemical Structure
Description
(E)-N-(4-(2-(((3-hydroxy-1-oxo-1H-inden-2-yl)methylene)amino)thiazol-4-yl)phenyl)acetamide (C21H15N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(E)-N-(4-(2-(((3-hydroxy-1-oxo-1H-inden-2-yl)methylene)amino)thiazol-4-yl)phenyl)acetamide (CAS 1024569-68-3), molecular formula C21H15N3O3S and molecular weight 389.43 g/mol, is a CATO reference standard with documented purity and traceability.
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.
