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 6,7-Dimethoxy-3,4-dihydroisoquinoline-2(1H)-sulfonamide.
6,7-Dimethoxy-3,4-dihydroisoquinoline-2(1H)-sulfonamide (CAS 1094222-85-1), molecular formula C11H16N2O4S and molecular weight 272.32 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H16N2O4S, 6,7-Dimethoxy-3,4-dihydroisoquinoline-2(1H)-sulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
