(3E,7E)-4,8-Dimethylnona-1,3,7-triene (CAS 19945-61-0) is an unsaturated building block of formula C11H18, 150.26 g/mol.
The double bond is the handle: epoxidation, dihydroxylation, hydrogenation and cross-metathesis all start here. The name fixes the geometry at C3, C7, so the entry is a defined isomer rather than a mixture and the lot is qualified on that isomer. The methyl branch at C8 changes how the chain packs, which shows up in melting behaviour and in the solubility of the free material.
The formula C11H18 resolves to 11 carbons with no heteroatom. A 11-carbon chain sits between volatility and lipophilicity, which is the range most often used when a fragment has to stay in the organic phase without being waxy.
Handling and storage
Olefins are stored closed and out of light; the isomer ratio is checked on receipt because it can drift on storage.
Ordering
Supplied in 1kg / 25kg / 100kg; a gram-scale sample is quoted against the same specification, so the analysis seen at sample stage is the analysis of the kilo lot.
