Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 331.41 g/mol gives Dopamine Impurity 119 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dopamine Impurity 119 (CAS 24997-85-1) is a certified pharmaceutical impurity reference standard with the molecular formula C19H25NO4 and a molecular weight of 331.41 g/mol.
Based on its molecular formula C19H25NO4, Dopamine Impurity 119 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 331.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 119 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.
