Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-Butyl 4-amino-1-azaspiro[5.5]undecane-1-carboxylate hydrochloride (CAS 1965309-66-3), molecular formula C15H28N2O2HCl and molecular weight 304.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl 4-amino-1-azaspiro[5.5]undecane-1-carboxylate hydrochloride (C15H28N2O2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
