Chemical Structure
Description
The occurrence of Ibuprofen Impurity 153 is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ibuprofen Impurity 153 (CAS CATO-C4X-1082153), a pharmacopoeial impurity reference standard (molecular formula C13H16Cl2O, MW 259.17 g/mol) used for the identification and quantification of trace impurities in APIs.
Ibuprofen Impurity 153 (C13H16Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
