Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Fingolimod EP impurity G is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.51 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).
CATO supplies Fingolimod EP impurity G (CAS 1807973-92-7), a pharmacopoeial impurity reference standard (molecular formula C21H35NO3, MW 349.51 g/mol) used for the identification and quantification of trace impurities in APIs.
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), Fingolimod EP impurity G 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.
