Compared with other compounds in its class, the molecular weight of 192.25 g/mol gives Alectinib Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Alectinib Impurity 5 (CAS 1247119-83-0) is a certified pharmaceutical impurity reference standard with the molecular formula C12H16O2 and a molecular weight of 192.25 g/mol.
Based on its molecular formula C12H16O2, Alectinib Impurity 5 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 192.25 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 Alectinib Impurity 5 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.
