Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 367.78 g/mol gives Epinephrine Impurity 63 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Epinephrine Impurity 63 HCl (CAS 1188265-23-7 (free base)), a pharmacopoeial impurity reference standard (molecular formula C17H17NO6HCl, MW 367.78 g/mol) used for the identification and quantification of trace impurities in APIs.
Epinephrine Impurity 63 HCl (C17H17NO6HCl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Epinephrine Impurity 63 HCl 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.
