Chemical Structure
Description
1H,2H,2aH,3H,4H,8bH-cyclobuta[a]naphthalen-2-amine hydrochloride (CAS 1989671-72-8), molecular formula C12H15NHCl and molecular weight 209.72 g/mol, is a CATO reference standard with documented purity and traceability.
1H,2H,2aH,3H,4H,8bH-cyclobuta[a]naphthalen-2-amine hydrochloride (C12H15NHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
