(3Z,6Z)-Nona-3,6-dien-1-ol

(3Z,6Z)-Nona-3,6-dien-1-ol (CAS 53046-97-2) is a C9H16O alcohol supplied in kilogram lots, from stock or made to order.

As a free alcohol it can be protected, activated as a leaving group or oxidised one step short of the acid, and the choice is usually decided by what has to survive afterwards. The name fixes the geometry at C3, C6, 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 C9H16O resolves to 9 carbons with one oxygen. A 9-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

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

Ordering

The unit weights held are 1kg / 25kg / 100kg. A split shipment across two of those sizes is treated as one lot and one certificate. Identity is confirmed by NMR and MS at release, and the assay value belongs to the lot rather than to the catalogue entry.
