Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cetylpyridinium Chloride Impurity 2.
As a process- or degradation-related impurity, Cetylpyridinium Chloride Impurity 2 (CAS CATO-C4X-27872, C19H34NClH2O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Cetylpyridinium Chloride Impurity 2 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Cetylpyridinium Chloride Impurity 2 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.
