Chemical Structure
Description
Cyclobenzaprine Impurity 3 (C15H11BrO) contains a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Cyclobenzaprine Impurity 3 (CAS 24167-44-0) is a certified pharmaceutical impurity reference standard with the molecular formula C15H11BrO and a molecular weight of 287.15 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 Cyclobenzaprine Impurity 3 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.
