CATO supplies Tiamulin EP Impurity O (CAS 100-38-9), a pharmacopoeial impurity reference standard (molecular formula C6H15NS, MW 133.26 g/mol) used for the identification and quantification of trace impurities in APIs.
Tiamulin EP Impurity O (C6H15NS) contains sulfur-containing functionality. Its physicochemical properties are representative of its class; 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.
As a certified reference material (CRM), Tiamulin EP Impurity O 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.
