Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.32 g/mol gives Tert-butyl (6-ethynylspiro[3.3]Heptan-2-yl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tert-butyl (6-ethynylspiro[3.3]Heptan-2-yl)carbamate (CAS 1809337-32-3), molecular formula C14H21NO2 and molecular weight 235.32 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tert-butyl (6-ethynylspiro[3.3]Heptan-2-yl)carbamate (C14H21NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 235.32 g/mol, it falls into the medium-molecular-weight range. 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.
