Chemical Structure
Description
CATO supplies Ethyl 2-acetamido-6-bromo-7-(3-hydroxy-2-methylpropoxy)benzo[b]thiophene-3-carboxylate (CAS 678148-16-8), a certified reference material (molecular formula C17H20BrNO5S, MW 430.31 g/mol) for analytical method development and quality control.
Ethyl 2-acetamido-6-bromo-7-(3-hydroxy-2-methylpropoxy)benzo[b]thiophene-3-carboxylate (C17H20BrNO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), Ethyl 2-acetamido-6-bromo-7-(3-hydroxy-2-methylpropoxy)benzo[b]thiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
