4-Oxodecanoic acid

Name: 4-Oxodecanoic acid
Brand: MedChemExpress
SKU: HY-W673672
Availability: PreOrder

(Synonyms: 4-Ketocapric acid; 4-ODA)

4-Oxodecanoic acid (4-Ketocapric acid) is a Sex pheromone component. 4-Oxodecanoic acid can be isolated from the sternal glands on the sixth abdominal segment of unmated female Vespa velutina. When mixed with 4-oxooctanoic acid at the natural secretion ratio of 0.78 in female wasps, 4-Oxodecanoic acid exhibits an attractive effect on male Vespa velutina. 4-Oxodecanoic acid can be used in population monitoring and control research on the invasive species Vespa velutina.

In Vivo

4-Oxodecanoic acid (10 ng-11.3 μg) triggers dose-dependent electrophysiological responses in male *Vespa velutina* at a dose of 10 ng; when mixed with 4-OOA at the natural ratio of female wasps (0.77 4-OOA/4-ODA), it acts as a highly efficient attractant for male wasps, with an attractiveness comparable to that of live virgin female wasps^[1].
The mixture of 4-Oxodecanoic acid (10 mg per trap; applied to filter paper), 4-OOA and 5-ODA at a ratio of 2:4:1 (4-OOA:4-ODA:5-ODA) exhibits extremely strong attractiveness to native male Vespa velutina nigrithorax in China^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

adult males^[1]
Dosage:

11.3 μg (blend with 8.7 μg 4-OOA); 10 ng, 100 ng, 1000 ng, 10,000 ng, 100,000 ng (antennal electrophysiology tests)
Administration:

delivered via filter paper attached to visual models, single application (blend); delivered via filter paper in odour-delivery pipettes, single puff exposure (antennal electrophysiology tests)
Result:

Exhibited dose-dependent electrophysiological responses to 4-ODA, with a significant response (vs. solvent control) observed at doses as low as 10 ng.
Attracted significantly more males than solvent controls when used in a natural gyne-derived ratio (11.3 μg 4-ODA + 8.7 μg 4-OOA, 0.77 ratio), with a number of landings not significantly different from those elicited by live virgin gynes.
Failed to attract significantly more males than controls when tested in ratios other than the natural gyne-derived ratio.

Animal Model:

yellow-legged hornet, native Chinese subspecies^[2]
Dosage:

10 mg per trap (in a 2:4:1 ratio with 4-OOA and 5-ODA)
Administration:

applied to filter paper
Result:

Attracted a mean of 93 males per day at Baiyunshan Park and 106 males per day at Longling Natural Reserve (ANOVA: F_(2,10) = 16.32, P < 0.001).
Attracted no males to solvent-only control traps.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
