(4E,7Z)-Trideca-4,7-dien-1-ol

(4E,7Z)-Trideca-4,7-dien-1-ol (CAS 57981-61-0) is a C13 alcohol with a 4E,7Z double-bond geometry used as a semiochemical component in surveillance and IPM work against Potato tuber moth and other species. It is a defined isomer rather than a mixture, which is what a blend specification normally asks for.

Our file records 2 targets for this material — Potato tuber moth (Phthorimaea operculella); Spotted tentiform leafminer (Phyllonorycter corylifoliella) — spanning tortricids and allies, other taxa. That is why it is held for surveillance and programme work rather than as general stock.

Programme use is blend-first. The compound is formulated with the other components recorded for the same complex, and the ratio — not the total loading — is what field results usually track.

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

Every lot ships with a certificate of analysis covering assay, isomeric composition and the chromatogram used to establish both. Safety data sheets are issued in the destination’s required language.

Standard packing for this line is 1kg / 25kg / 100kg, with smaller development quantities available so a blend can be trialled before a bulk order. Lead time is confirmed at quotation.

Target species recorded against this compound

• Potato tuber moth Phthorimaea operculella
• Spotted tentiform leafminer Phyllonorycter corylifoliella

Species records are drawn from the blend literature filed for this material. Where a programme targets a species not listed, the blend is usually a ratio question rather than a different compound — send the target and we will confirm.
