Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 195.22 g/mol gives Dopamine Impurity 63 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dopamine Impurity 63 (CAS 5663-55-8) is a certified pharmaceutical impurity reference standard with the molecular formula C10H13NO3 and a molecular weight of 195.22 g/mol.
Dopamine Impurity 63 (C10H13NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Dopamine Impurity 63 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.
