Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 205.70 g/mol gives Duloxetine Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Duloxetine Impurity 5 (CAS 645411-16-1), molecular formula C8H11NOSHCl and molecular weight 205.70 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H11NOSHCl, Duloxetine Impurity 5 contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Duloxetine Impurity 5 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.
