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-amino-2-(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)acetate hydrochloride (CAS 147900-32-1) is a high-purity analytical reference standard with the molecular formula C19H21NO2HCl and a molecular weight of 331.84 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-amino-2-(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)acetate hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.84 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).
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.
