CATO supplies 5-Oxo-1-(3-oxo-1,3-dihydro-2-benzofuran-1-yl)-D-proline (CAS 1217542-54-5), a certified reference material (molecular formula C13H11NO5, MW 261.23 g/mol) for analytical method development and quality control.
5-Oxo-1-(3-oxo-1,3-dihydro-2-benzofuran-1-yl)-D-proline (C13H11NO5) contains a nitrogen-containing heterocyclic scaffold, 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. 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.
