(3E,8Z,11Z)-Tetradeca-3,8,11-trien-1-yl acetate

(3E,8Z,11Z)-Tetradeca-3,8,11-trien-1-yl acetate (CAS 163041-94-9) is a C14 acetate ester with a 3E,8Z,11Z 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.

Most orders are recurring: the same isomer, the same packing, the same certificate layout, season after season. Consistency between lots is the point of buying it against a specification rather than against a price list.

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

Each delivery carries a certificate of analysis, a GC trace and an SDS. Where a tender asks for method detail, the chromatographic conditions are supplied separately on request.

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.
