Chemical Structure
Description
CATO supplies Ethyl 3-((4-(2,3-dimethylphenyl)piperazin-1-yl)sulfonyl)benzo[b]thiophene-2-carboxylate (CAS 895266-87-2), a certified reference material (molecular formula C23H26N2O4S2, MW 458.59 g/mol) for analytical method development and quality control.
Ethyl 3-((4-(2,3-dimethylphenyl)piperazin-1-yl)sulfonyl)benzo[b]thiophene-2-carboxylate (C23H26N2O4S2) contains a flavonoid 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).
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.
