(2E,4E,6Z)-Methyl deca-2,4,6-trienoate

(2E,4E,6Z)-Methyl deca-2,4,6-trienoate (CAS 51544-64-0) is a C10 ester with a 2E,4E,6Z double-bond geometry used as a semiochemical component in surveillance and IPM work against Brown-winged green bug. 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 Brown-winged green bug (Plautia stali) — which is why the material is held for surveillance work rather than as general stock.

It goes into lures and into analytical standards. The same lot can serve both, which helps when a programme needs to compare trap catches against a reference chromatogram.

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

Esters in this list are judged mainly on isomeric purity. The minor isomer is a different semiochemical and can suppress rather than support attraction, which is why isomer figures belong in the specification.

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 / 100kg, with smaller development quantities available so a blend can be trialled before a bulk order. Lead time is confirmed at quotation.

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.
