Chemical Structure
Description
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.
Dihydro ketoprofen β-D-glucuronide, 98% (CAS 849104-47-8), molecular formula C22H24O9 and molecular weight 432.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dihydro ketoprofen β-D-glucuronide, 98% (C22H24O9) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Dihydro ketoprofen β-D-glucuronide, 98% 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.
