Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 316.15 g/mol gives Netupitant Impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Netupitant Impurity 31 (CAS 1444338-30-0) is a certified pharmaceutical impurity reference standard with the molecular formula C11H6F6O4 and a molecular weight of 316.15 g/mol.
Based on its molecular formula C11H6F6O4, Netupitant Impurity 31 contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 316.15 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 Netupitant Impurity 31 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.
