Compared with other compounds in its class, the molecular weight of 246.26 g/mol gives Iobitridol Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Iobitridol Impurity 22 (CAS CATO-C4X-317822), a pharmacopoeial impurity reference standard (molecular formula C11H18O6, MW 246.26 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C11H18O6, Iobitridol Impurity 22 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 246.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Iobitridol Impurity 22 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.
