(E)-11-Tetradecen-1-ol

(E)-11-Tetradecen-1-ol (CAS 35153-18-5) is a C14 alcohol used as a female sex pheromone component in surveillance and IPM work against Spruce budworm and other species.

Our file records 13 targets for this material — Spruce budworm; Tufted apple budmoth; Omnivorous leafroller; Light brown apple moth; Obliquebanded leafroller; Jack pine budworm and other species in the same group — spanning moths, tortricids and allies. That is why it is held for surveillance and programme work rather than as general stock.

In practice it is used as one component of a multi-component blend rather than on its own: loaded on a rubber septum, a polyethylene vial or a membrane dispenser, then deployed with the trap type that suits the target’s flight behaviour.

Inside a budworm or leafroller programme

Tortricid sex pheromones are almost always multi-component, and the ratios carry the species message. (E)-11-Tetradecen-1-ol is one of the components used to build those ratios. A blend that is right for one species in a stand can be close to useless for a congener fifty metres away, which is why programmes run species-specific blends side by side rather than one broad-spectrum lure.

Catch is read as a trend across weeks: the first sustained catch dates the flight, the peak dates the window for any intervention, and the tail of the curve tells you whether a second generation is present.

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.
