Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 377.86 g/mol gives (+)-Isocorydine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (+)-Isocorydine hydrochloride (CAS 13552-72-2), a certified reference material (molecular formula C20H23NO4HCl, MW 377.86 g/mol) for analytical method development and quality control.
(+)-Isocorydine hydrochloride (C20H23NO4HCl) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (+)-Isocorydine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
