Chemical Structure

Duloxetine Impurity 17 CAS 116817-84-6 chemical structure

Description

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.

Duloxetine Impurity 17 (CAS 116817-84-6) is a certified pharmaceutical impurity reference standard with the molecular formula C9H15NOS and a molecular weight of 185.29 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Duloxetine Impurity 17 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
