Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methylumbelliferyl a-L-Idopyranosiduronic Acid Methyl Ester.
4-Methylumbelliferyl a-L-Idopyranosiduronic Acid Methyl Ester (CAS 128095-52-3), molecular formula C23H24O12 and molecular weight 492.43 g/mol, is a CATO reference standard with documented purity and traceability.
4-Methylumbelliferyl a-L-Idopyranosiduronic Acid Methyl Ester (C23H24O12) contains a flavonoid core, a hydroxyl group, an ether linkage. 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-Methylumbelliferyl a-L-Idopyranosiduronic Acid Methyl Ester 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.
