Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 565.12 g/mol gives Tianeptin EP Impurity E distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tianeptin EP Impurity E (CAS 768351-55-9), a certified reference material (molecular formula C28H37ClN2O6S, MW 565.12 g/mol) for analytical method development and quality control.
Tianeptin EP Impurity E (C28H37ClN2O6S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
