Description
CATO supplies Elagolix Impurity 25 (CAS 832720-51-1), a pharmacopoeial impurity reference standard (molecular formula C31H28F5N3O5, MW 617.56 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Elagolix Impurity 25 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 617.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Elagolix Impurity 25 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.
