(3E,8Z)-Tetradeca-3,8-dien-1-yl acetate

(3E,8Z)-Tetradeca-3,8-dien-1-yl acetate (CAS 163041-87-0) is a C14 acetate ester with a 3E,8Z double-bond geometry used as a semiochemical component in surveillance and IPM work against Tomato leafminer 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 — Tomato leafminer; Tomato leafminer (Tuta absoluta) — spanning other taxa, tortricids and allies. That is why it is held for surveillance and programme 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

Acetates hydrolyse slowly in the presence of moisture and are the class most disturbed by warm storage. Lot history — how the material has been held since manufacture — matters more than the headline assay.

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.

Target species recorded against this compound

• Tomato leafminer
• Tomato leafminer Tuta absoluta

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.
