Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 301.38 g/mol gives Etodolac EP Impurity F distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Etodolac EP Impurity F (CAS 849630-65-5) is a certified pharmaceutical impurity reference standard with the molecular formula C18H23NO3 and a molecular weight of 301.38 g/mol.
Structurally, Etodolac EP Impurity F (C18H23NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 301.38 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Etodolac EP Impurity F 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.
