Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 433.58 g/mol gives Fingolimod EP Impurity H distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Fingolimod EP Impurity H (CAS 162358-09-0, C25H39NO5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Fingolimod EP Impurity H (C25H39NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Fingolimod EP Impurity H 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.
