Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 354.44 g/mol gives Phenylbutyrate Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Phenylbutyrate Impurity 11 (CAS CATO-C4X-258311, C22H26O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Phenylbutyrate Impurity 11 (C22H26O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures Phenylbutyrate 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.
