The occurrence of 1-(4-((6,7-Dimethoxy-3,4-dihydroisoquinolin-1-yl)methyl)phenyl)-3-(3-fluoro-4-methylphenyl)urea is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(4-((6,7-Dimethoxy-3,4-dihydroisoquinolin-1-yl)methyl)phenyl)-3-(3-fluoro-4-methylphenyl)urea (CAS 1023435-48-4), molecular formula C26H26FN3O3 and molecular weight 447.50 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(4-((6,7-Dimethoxy-3,4-dihydroisoquinolin-1-yl)methyl)phenyl)-3-(3-fluoro-4-methylphenyl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 447.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
