Chemical Structure
Description
As a certified reference material (CRM), 3-Ethyl-4-methoxy-7-methylbenzo[d]thiazol-2(3H)-imine 4-methylbenzenesulfonate 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.
CATO supplies 3-Ethyl-4-methoxy-7-methylbenzo[d]thiazol-2(3H)-imine 4-methylbenzenesulfonate (CAS 2034154-92-0), a certified reference material (molecular formula C11H14N2OSC7H8O3S, MW 394.50 g/mol) for analytical method development and quality control.
3-Ethyl-4-methoxy-7-methylbenzo[d]thiazol-2(3H)-imine 4-methylbenzenesulfonate (C11H14N2OSC7H8O3S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
