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.
CATO supplies (R)-Flurbiprofen Axetil (Mixture of Diastereomers) (CAS 2375240-97-2), a certified reference material (molecular formula C19H19FO4, MW 330.35 g/mol) for analytical method development and quality control.
Structurally, (R)-Flurbiprofen Axetil (Mixture of Diastereomers) (C19H19FO4) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 330.35 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (R)-Flurbiprofen Axetil (Mixture of Diastereomers) 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.
