Chemical Structure
Description
The occurrence of Benzalkonium Chloride impurity 5 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 5 (CAS 41961-81-3), a pharmacopoeial impurity reference standard (molecular formula C29H61N, MW 423.80 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Benzalkonium Chloride impurity 5 (C29H61N) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 423.80 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), Benzalkonium Chloride impurity 5 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
