(S,1E,5E)-1,5-Dimethyl-8-(prop-1-en-2-yl)cyclodeca-1,5-diene CAS 28387-44-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(S,1E,5E)-1,5-Dimethyl-8-(prop-1-en-2-yl)cyclodeca-1,5-diene (CAS 28387-44-2), molecular formula C15H24 and molecular weight 204.35 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S,1E,5E)-1,5-Dimethyl-8-(prop-1-en-2-yl)cyclodeca-1,5-diene (C15H24) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 204.35 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.

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.
