Chemical Structure
Description
CATO supplies 5-Cyclopropyl-4,5-dihydro-3H-spiro[benzo[b][1,4]oxazepine-2,4'-piperidine] (CAS 1956331-87-5), a certified reference material (molecular formula C16H22N2O, MW 258.36 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, 5-Cyclopropyl-4,5-dihydro-3H-spiro[benzo[b][1,4]oxazepine-2,4'-piperidine] is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.36 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.
