Duloxetine Impurity 16 CAS 13636-02-7 chemical structure

Description

CATO supplies Duloxetine Impurity 16 (CAS 13636-02-7), a pharmacopoeial impurity reference standard (molecular formula C9H15NOS, MW 185.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Duloxetine Impurity 16 (C9H15NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
