4-(4-(Benzyloxy)-2-methylbenzoyl)-3-hydroxy-5-(4-hydroxy-3-methoxyphenyl)-1-(pyridin-3-ylmethyl)-1H-pyrrol-2(5H)-one (CAS 500274-51-1), molecular formula C32H28N2O6 and molecular weight 536.57 g/mol, is a CATO reference standard with documented purity and traceability.
4-(4-(Benzyloxy)-2-methylbenzoyl)-3-hydroxy-5-(4-hydroxy-3-methoxyphenyl)-1-(pyridin-3-ylmethyl)-1H-pyrrol-2(5H)-one (C32H28N2O6) 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. 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.
As a certified reference material (CRM), 4-(4-(Benzyloxy)-2-methylbenzoyl)-3-hydroxy-5-(4-hydroxy-3-methoxyphenyl)-1-(pyridin-3-ylmethyl)-1H-pyrrol-2(5H)-one 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.
