5-(5-Bromo-3-methoxy-2-(prop-2-yn-1-yloxy)benzylidene)thiazolidine-2,4-dione CAS 591745-14-1

Description

As a certified reference material (CRM), 5-(5-Bromo-3-methoxy-2-(prop-2-yn-1-yloxy)benzylidene)thiazolidine-2,4-dione 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.

5-(5-Bromo-3-methoxy-2-(prop-2-yn-1-yloxy)benzylidene)thiazolidine-2,4-dione (CAS 591745-14-1), molecular formula C14H10BrNO4S and molecular weight 368.20 g/mol, is a CATO reference standard with documented purity and traceability.

5-(5-Bromo-3-methoxy-2-(prop-2-yn-1-yloxy)benzylidene)thiazolidine-2,4-dione (C14H10BrNO4S) contains a nitrogen-containing heterocyclic scaffold, 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, 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.
