Chemical Structure
Description
CATO manufactures Lemborexant Impurity 86 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.
CATO supplies Lemborexant Impurity 86 (CAS CATO-C4X-304286), a pharmacopoeial impurity reference standard (molecular formula C13H15FO3, MW 238.25 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Lemborexant Impurity 86 (C13H15FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 238.25 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
