Chemical Structure
Description
The occurrence of Benzalkonium Chloride impurity 7 is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Benzalkonium Chloride impurity 7 (CAS 14727-68-5), a pharmacopoeial impurity reference standard (molecular formula C20H41N, MW 295.55 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Benzalkonium Chloride impurity 7 (C20H41N) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
