Chemical Structure
Description
The occurrence of 6,7,8-trimethoxy-2,3,4,5-tetrahydro-1H-3-benzazepin-2-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6,7,8-trimethoxy-2,3,4,5-tetrahydro-1H-3-benzazepin-2-one (CAS 1421602-05-2), a certified reference material (molecular formula C13H17NO4, MW 251.28 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 6,7,8-trimethoxy-2,3,4,5-tetrahydro-1H-3-benzazepin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 251.28 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.
