2-Methyl-6-methyleneocta-2,7-dien-4-ol

2-Methyl-6-methyleneocta-2,7-dien-4-ol (CAS 14434-41-4) is a C8 alcohol used as a semiochemical component in surveillance and IPM work against Ips bark beetles.

The only target recorded in our file is Ips bark beetles (Ips spp.) — 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

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

Documentation is lot-based: certificate of analysis, GC trace and safety data sheet travel with the consignment, and an isomer-ratio statement can be added where a specification calls for it.

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.
