Chemical Structure

2-Pentylidenecyclohexanone CAS 25677-40-1 chemical structure

Description

The occurrence of 2-Pentylidenecyclohexanone is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Pentylidenecyclohexanone (CAS 25677-40-1), molecular formula C11H18O and molecular weight 166.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Pentylidenecyclohexanone (C11H18O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 166.26 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.
