3-Ethyl-2-((3-ethyl-5-(2-(1-ethylquinolin-4(1H)-ylidene)ethylidene)-4-oxothiazolidin-2-ylidene)methyl)-4,5-diphenylthiazol-3-ium bromide CAS 51257-37-5 chemical structure

Description

CATO supplies 3-Ethyl-2-((3-ethyl-5-(2-(1-ethylquinolin-4(1H)-ylidene)ethylidene)-4-oxothiazolidin-2-ylidene)methyl)-4,5-diphenylthiazol-3-ium bromide (CAS 51257-37-5), a certified reference material (molecular formula C36H34N3OS2Br, MW 668.71 g/mol) for analytical method development and quality control.

3-Ethyl-2-((3-ethyl-5-(2-(1-ethylquinolin-4(1H)-ylidene)ethylidene)-4-oxothiazolidin-2-ylidene)methyl)-4,5-diphenylthiazol-3-ium bromide (C36H34N3OS2Br) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
