(11Z,13Z)-Hexadecadien-1-ol

(11Z,13Z)-Hexadecadien-1-ol (CAS 71720-83-7) is a C16 alcohol with a 11Z,13Z double-bond geometry used as a semiochemical component in surveillance and IPM work against Navel orangeworm. It is a defined isomer rather than a mixture, which is what a blend specification normally asks for.

The only target recorded in our file is Navel orangeworm (Amyelois transitella) — which is why the material is held for surveillance work rather than as general stock.

It is supplied for formulation and for reference work: blend development, release-rate trials, and the isomer-ratio checks that quality systems ask for before a season starts.

Where it is used

This material sits in the working part of the catalogue: the compounds formulation teams ask for by CAS when a blend needs a specific isomer, a reference point for a chromatogram, or a small quantity to test before committing to a drum.

Isomer, stability and handling

Alcohols are comparatively stable but hygroscopic. Small water uptake is enough to move a release rate over a long flight season, so keep containers sealed and dry between weighing operations.

Store cool, dry and dark: sealed under nitrogen or argon at −20 °C for holdings longer than one season, and let containers reach room temperature before opening so condensation does not enter the material. Weigh and formulate in a ventilated area; the safety data sheet gives handling detail for the neat substance.

Documentation and packing

Paperwork is deliberately boring: certificate of analysis with assay and isomer figures, GC trace, SDS and packing list. Nothing is quoted that cannot be reproduced on a rerun.

Standard packing for this line is 1kg / 25kg / 50kg, with smaller development quantities available so a blend can be trialled before a bulk order. Lead time is confirmed at quotation.
