Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 320.47 g/mol gives Mutilin (Tiamulin EP Impurity A) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Mutilin (Tiamulin EP Impurity A) (CAS 6040-37-5), a pharmacopoeial impurity reference standard (molecular formula C20H32O3, MW 320.47 g/mol) used for the identification and quantification of trace impurities in APIs.
Mutilin (Tiamulin EP Impurity A) (C20H32O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Mutilin (Tiamulin EP Impurity A) 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.
