CATO supplies 3-(4-Methyl-2,5-dioxo-2,5-dihydrofuran-3-yl)propanoic acid (CAS 487-66-1), a certified reference material (molecular formula C8H8O5, MW 184.15 g/mol) for analytical method development and quality control.
3-(4-Methyl-2,5-dioxo-2,5-dihydrofuran-3-yl)propanoic acid (C8H8O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
