Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.26 g/mol gives Gliquidone Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Gliquidone Impurity 4 (CAS 191988-38-2) is a certified pharmaceutical impurity reference standard with the molecular formula C13H15NO3 and a molecular weight of 233.26 g/mol.
Gliquidone Impurity 4 (C13H15NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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 Gliquidone 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.
