Duloxetine EP Impurity C CAS 949095-98-1

Description

Compared with other compounds in its class, the molecular weight of 297.41 g/mol gives Duloxetine EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Duloxetine EP Impurity C (CAS 949095-98-1), a pharmacopoeial impurity reference standard (molecular formula C18H19NOS, MW 297.41 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Duloxetine EP Impurity C (C18H19NOS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Duloxetine EP Impurity C 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.
