(Also known as: Straight Chain Lepidopteran Pheromone; SCLP; (E)-dec-5-enyl acetate; Peach tree borer sex pheromone; (E)5-10Ac; Oriental fruit moth pheromone)
SUMMARY
Hazard alerts
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.
A volatile substance that is classed as a Straight Chain Lepidopteran Pheromone (SCLP) and used as an insect attractant
Example pests controlled
Various insects belong to the Lepidoptera order including the codling moth (Cydia pomonella), pandemis leafroller (Pandemis pyrusana) and the fruit tree leafroller (Archips argyrospilus)
Example applications
Top fruit; Stone fruit; Tree nuts

Chemical structure
Isomerism
(E)-dec-5-enyl acetate exhibits geometric (cis/trans or E/Z) isomerism, centred around its carbon–carbon double bond at the 5th position of the decenyl chain.

Formulation and application details
Usually supplied in slow release formulations
Commercial production
The synthesis of (E)-dec-5-enyl acetate begins with a suitable starting material, often a long-chain alkene or alkyne which undergoes hydroformylation, a process that adds a formyl group (CHO) to the carbon chain, resulting in an aldehyde intermediate. The aldehyde intermediate is then reduced to the corresponding alcohol using a reducing agent such as sodium borohydride or lithium aluminium hydride. The resulting alcohol is subjected to isomerisation to ensure the double bond is in the correct position (at the 5th carbon) and in the desired configuration (cis or Z). Finally, the alcohol is acetylated to form the acetate ester, (E)-dec-5-enyl acetate. This step can be achieved using acetic anhydride or acetyl chloride in the presence of a catalyst. It is then purified.
Impact on climate of production and use
While exact CO₂e values are not published for specific pheromones, some general information is available. The PHERA reported that biotechnological production (e.g. yeast fermentation) of pheromones can reduce GHG emissions by up to 90% compared to traditional chemical synthesis and GHG emissions are typically in the 5 to 10 kg CO₂e per kg of pheromone produced. Other sources suggest that small scale pheromone synthesis typically has emissions in the range 1 – 3 kg CO₂e per kg of pheromone produced.
