Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 466.08 g/mol gives Rimegepant Impurity 19 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Rimegepant Impurity 19 (CAS 1289024-04-9) is a certified pharmaceutical impurity reference standard with the molecular formula C25H34ClF2NOSi and a molecular weight of 466.08 g/mol.
Structurally, Rimegepant Impurity 19 (C25H34ClF2NOSi) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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 466.08 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.
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.
CATO manufactures Rimegepant Impurity 19 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
