Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.40 g/mol gives tert-butyl 9-methyl-3,9-diazaspiro[5.5]undecane-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-butyl 9-methyl-3,9-diazaspiro[5.5]undecane-3-carboxylate (CAS 918653-13-1), molecular formula C15H28N2O2 and molecular weight 268.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, tert-butyl 9-methyl-3,9-diazaspiro[5.5]undecane-3-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.40 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.
