Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 338.98 g/mol gives Cetylpyridinium Chloride Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Cetylpyridinium Chloride Impurity 4 (CAS CATO-C4X-27874, C21H37ClN) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Cetylpyridinium Chloride Impurity 4 (C21H37ClN) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Cetylpyridinium Chloride Impurity 4 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.
