(S)-(-)-Ipsenol
(S)-(-)-Ipsenol (CAS 35628-05-8) is an alcohol used as an aggregation pheromone component in lures, release-rate trials and reference work.
No target species is recorded against this material in our file, so it is catalogued as a blend component and reference material. If a specification needs species named, send the target and we will confirm whether this isomer is the right starting point.
Inside a bark beetle programme
Aggregation signals of Ips and allied Scolytinae are deployed as a three-part message: the terpene alcohols the beetle produces itself, a host monoterpene such as alpha-pinene or a blend with ethanol, and a trap geometry that matches the beetle’s landing behaviour. (S)-(-)-Ipsenol belongs in the first part. Because the response is synergistic, changing the host-volatile side usually moves catches further than changing the pheromone loading.
For a survey grid the variables that matter are trap spacing, trap height and the date traps go up relative to swarming. For delimitation work it is spacing plus the number of consecutive flight periods covered. Both are decided per stand and per national guidance, not per catalogue entry.
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
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.
