2-(5-Bromo-2-methoxybenzylidene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one CAS 329718-84-5

Description

2-(5-Bromo-2-methoxybenzylidene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (CAS 329718-84-5), molecular formula C17H11BrN2O2S and molecular weight 387.25 g/mol, is a CATO reference standard with documented purity and traceability.

2-(5-Bromo-2-methoxybenzylidene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (C17H11BrN2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

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), 2-(5-Bromo-2-methoxybenzylidene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one 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.
