Chemical Structure
Description
Tiamulin EP Impurity E Fumarate (CAS CATO-C4X-22106) is a certified pharmaceutical impurity reference standard with the molecular formula C28H45NO4SC4H4O4 and a molecular weight of 607.80 g/mol.
The molecular framework of Tiamulin EP Impurity E Fumarate (C28H45NO4SC4H4O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Tiamulin EP Impurity E Fumarate 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.
