Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl (2-oxo-2,3,4,5-tetrahydro-1H-benzo[d]azepin-1-yl)carbamate (CAS 209983-86-8) is a high-purity analytical reference standard with the molecular formula C13H16N2O3 and a molecular weight of 248.28 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Ethyl (2-oxo-2,3,4,5-tetrahydro-1H-benzo[d]azepin-1-yl)carbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.28 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).
CATO manufactures Ethyl (2-oxo-2,3,4,5-tetrahydro-1H-benzo[d]azepin-1-yl)carbamate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
