Chemical Structure
Description
The occurrence of Isofluorane Impurity 5 is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Isofluorane Impurity 5 (CAS 32778-08-8) is a certified pharmaceutical impurity reference standard with the molecular formula C3HCl2F5O and a molecular weight of 218.94 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Isofluorane Impurity 5 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Isofluorane 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.
