Chemical Structure

Biotin EP Impurity G Bromide CAS 33719-11-8 chemical structure

Description

The occurrence of Biotin EP Impurity G Bromide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Biotin EP Impurity G Bromide (CAS 33719-11-8, C22H25N2OSBr) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Biotin EP Impurity G Bromide (C22H25N2OSBr) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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 Biotin EP Impurity G Bromide 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.
