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 Pimavanserin Impurity 25 (CAS CATO-C4X-193825), a pharmacopoeial impurity reference standard (molecular formula C11H17NOHCl, MW 215.72 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Pimavanserin Impurity 25 is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 215.72 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.
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.
