Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 382.51 g/mol gives Flurbiprofen Menthyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Flurbiprofen Menthyl Ester (CAS 908559-44-4), molecular formula C25H31FO2 and molecular weight 382.51 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Flurbiprofen Menthyl Ester (C25H31FO2) contains a steroid 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 382.51 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Flurbiprofen Menthyl 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.
