13a-hydroxy-9,10-dimethoxy-7-methyl-5,6,7,8,13,13a-hexahydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium chloride CAS 63251-92-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 13a-hydroxy-9,10-dimethoxy-7-methyl-5,6,7,8,13,13a-hexahydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium chloride.

13a-hydroxy-9,10-dimethoxy-7-methyl-5,6,7,8,13,13a-hexahydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium chloride (CAS 63251-92-3), molecular formula C21H24NO5Cl and molecular weight 405.88 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 13a-hydroxy-9,10-dimethoxy-7-methyl-5,6,7,8,13,13a-hexahydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium chloride (C21H24NO5Cl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 13a-hydroxy-9,10-dimethoxy-7-methyl-5,6,7,8,13,13a-hexahydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium chloride 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.
