Fluoxetine EP Impurity B CAS 23580-89-4 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.

CATO supplies Fluoxetine EP Impurity B (CAS 23580-89-4), a pharmacopoeial impurity reference standard (molecular formula C10H15N, MW 149.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Fluoxetine EP Impurity B (C10H15N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
