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 1-(4,5-Dimethoxy-2-nitrobenzyl)-6,7-dimethoxyisoquinoline.
1-(4,5-Dimethoxy-2-nitrobenzyl)-6,7-dimethoxyisoquinoline (CAS 25944-25-6), molecular formula C24H46NO2Br and molecular weight 460.54 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(4,5-Dimethoxy-2-nitrobenzyl)-6,7-dimethoxyisoquinoline (C24H46NO2Br) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 460.54 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1-(4,5-Dimethoxy-2-nitrobenzyl)-6,7-dimethoxyisoquinoline 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.
