Chemical Structure

3-(tert-Butyl)cyclopent-2-en-1-one CAS 5682-70-2 chemical structure

Description

The occurrence of 3-(tert-Butyl)cyclopent-2-en-1-one is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(tert-Butyl)cyclopent-2-en-1-one (CAS 5682-70-2), molecular formula C9H14O and molecular weight 138.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, 3-(tert-Butyl)cyclopent-2-en-1-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.21 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.
