Compared with other compounds in its class, the molecular weight of 285.40 g/mol gives Sevoflurane Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sevoflurane Impurity 11 (CAS 33034-42-3) is a certified pharmaceutical impurity reference standard with the molecular formula C4HCl3F6O and a molecular weight of 285.40 g/mol.
Based on its molecular formula C4HCl3F6O, Sevoflurane Impurity 11 contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 285.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Sevoflurane Impurity 11 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.
