(3Z,13Z)-Octadeca-3,13-dien-1-ol

(3Z,13Z)-Octadeca-3,13-dien-1-ol is an alcohol entry in the catalogue: CAS 66410-24-0, C18H34O, molecular weight 266.5.

The hydroxyl is the handle: acylation, oxidation, ether formation and Mitsunobu displacement are the reactions this entry is normally bought for. The name fixes the geometry at C3, C13, so the entry is a defined isomer rather than a mixture and the lot is qualified on that isomer. More than one double bond means the isomer pattern, not the chain length, is what the downstream separation has to resolve.

The formula C18H34O resolves to 18 carbons with one oxygen. Long-chain entries of 18 carbons behave as oils or waxy solids and are warmed before packing so that the unit weight is accurate.

Handling and storage

Alcohols of this size are hygroscopic. Where the step is moisture sensitive the lot is dried over a molecular sieve before charging.

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.
