Chemical Structure
Description
ETHYL 2-(BENZO[B]THIOPHEN-3-YL)-2-(DIMETHYLAMINO)ACETATE (CAS 1007885-53-1), molecular formula C14H17NO2S and molecular weight 263.36 g/mol, is a CATO reference standard with documented purity and traceability.
ETHYL 2-(BENZO[B]THIOPHEN-3-YL)-2-(DIMETHYLAMINO)ACETATE (C14H17NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
