Chemical Structure

Benzalkonium Chloride impurity 11 CAS 45275-74-9 chemical structure

Description

Structurally, Benzalkonium Chloride impurity 11 (C22H47N) 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 325.62 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.

Benzalkonium Chloride impurity 11 (CAS 45275-74-9) is a certified pharmaceutical impurity reference standard with the molecular formula C22H47N and a molecular weight of 325.62 g/mol.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Benzalkonium Chloride impurity 11 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
