Chemical Structure
Description
The occurrence of tert-Butyl 2-(diphenylmethyleneamino)-7,8-dihydro-1,6-naphthyridine-6(5H)-carboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl 2-(diphenylmethyleneamino)-7,8-dihydro-1,6-naphthyridine-6(5H)-carboxylate (CAS 1346673-94-6), molecular formula C26H27N3O2 and molecular weight 413.51 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, tert-Butyl 2-(diphenylmethyleneamino)-7,8-dihydro-1,6-naphthyridine-6(5H)-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 413.51 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.
