CATO supplies (S)-1-(1-Carboxy-3-methylbutyl)-3-mesityl-1H-imidazol-3-iumacetate (CAS 1643854-06-1), a certified reference material (molecular formula C18H25N2O2C2H3O2, MW 360.45 g/mol) for analytical method development and quality control.
(S)-1-(1-Carboxy-3-methylbutyl)-3-mesityl-1H-imidazol-3-iumacetate (C18H25N2O2C2H3O2) contains a flavonoid core, an amide 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 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.
