Chemical Structure

Milnacipran impurity 28 CAS 136090-97-6 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Milnacipran impurity 28 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 218.29 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.

CATO supplies Milnacipran impurity 28 (CAS 136090-97-6), a pharmacopoeial impurity reference standard (molecular formula C13H18N2O, MW 218.29 g/mol) used for the identification and quantification of trace impurities in APIs.

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.

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.
