Chemical Structure
Description
1-(2-(1H-imidazol-1-yl)ethyl)-3-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)urea (CAS 1311681-72-7) is a high-purity analytical reference standard with the molecular formula C18H25N5O2 and a molecular weight of 343.42 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-(2-(1H-imidazol-1-yl)ethyl)-3-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
