tert-butyl 6-bromo-2-azaspiro[3.3]heptane-2-carboxylate CAS 2409962-67-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 276.17 g/mol gives tert-butyl 6-bromo-2-azaspiro[3.3]heptane-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-butyl 6-bromo-2-azaspiro[3.3]heptane-2-carboxylate (CAS 2409962-67-8), molecular formula C11H18BrNO2 and molecular weight 276.17 g/mol, is a CATO reference standard with documented purity and traceability.

tert-butyl 6-bromo-2-azaspiro[3.3]heptane-2-carboxylate (C11H18BrNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
