Chemical Structure

Lubiprostone Impurity 35 CAS 1808535-45-6 (Cyclo Form) chemical structure

Description

Lubiprostone Impurity 35 (C20H32F2O5) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Lubiprostone Impurity 35 (CAS 1808535-45-6 (Cyclo Form)) is a certified pharmaceutical impurity reference standard with the molecular formula C20H32F2O5 and a molecular weight of 390.46 g/mol.

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 Lubiprostone Impurity 35 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.
