(7Z,9E)-Dodeca-7,9-dienyl acetate (CAS 54364-62-4): acetate ester for conjugated diene lures, packed to order with COA and SDS on every lot.
A twelve-carbon dienyl acetate with the conjugated pair at C7 and C9, in the (7Z,9E) configuration. Short chains of this kind release quickly from a matrix, which is why the dispenser is chosen with the compound in mind and why a load rate copied from a longer-chain acetate rarely transfers. We would rather fix the specification first and quote second; that order removes the sample, re-sample, re-quote loop.

An acetate ester, chemically
The ester linkage moderates the polarity of the chain, which is why acetates release more evenly from rubber and polymer matrices than the parent alcohols and are the backbone of many moth lures. The same linkage hydrolyses under acidic or basic conditions, so the carrier and any water in the system matter.
Stability in storage and on the dispenser
Hydrolysis and oxidation are the two ageing routes. Keep the material dry, sealed and away from acidic or basic contamination, and the lot will outlast a season; leave it in a humid store and the free acid will appear on the next chromatogram.
What the analytics have to show
Assay, isomeric ratio and the free-acid figure. For a dienyl acetate the geometry of the conjugated system is part of identity, not a detail: two lots with the same assay and a different E/Z split are not interchangeable.
Working with a distributor
Where the material moves through a distributor, the documentation still originates with the batch. Ask for the original certificate rather than a transcribed one — a retyped COA loses the method reference that makes it useful.
Isomeric form
If your formulation was developed against a particular ratio, state it: matching an existing blend is easier than re-optimising one. This entry is the (7Z,9E) form. The lot is released against that descriptor, and the ratio of the named isomer to its partner is stated on the certificate.
Load rate and blend position
Most first orders repeat the trial quantity, then move to bulk once the blend is stable. Both are quoted, and neither is treated as an afterthought.
Packing and lot size
This compound ships in 1kg / 25kg / 100kg. Where a process needs a narrower unit weight, the packing is agreed with the order rather than read off the catalogue.
Documentation
If your QA department needs the analytical method named, or a chromatogram attached, ask at enquiry stage and it travels with the lot documents.
Ordering
The form on this page reaches a technical desk, not a general inbox, and it is answered within one business day.
What the analytical package covers
Where a customer runs a different GC method, the two results rarely agree to the decimal. Agreeing the method at order stage is cheaper than reconciling two certificates later.
Release rate and dispenser matching
Release rate is set by the dispenser and the carrier, not by the active alone. A rubber septum, a polymer matrix and a liquid formulation each release the same compound at a different rate, so a load rate borrowed from another dispenser type is a starting point and not an answer.
Registration and destination paperwork
Nothing on this page is a regulatory claim. Where a registration exists for a market we will say so in writing; where it does not, the customer’s own registration work is what the shipment depends on.
Compatibility with carriers and dispensers
Where a customer supplies the matrix, we can quote the material against its compatibility rather than in isolation — that conversation is worth having before the first order, not after the first failed trial.
Fitment: the four questions
Fitment questions about a lure active are really specification questions: which blend, which dispenser, which target, which season. Send those four and the reply is specific; send a compound name alone and it can only be generic.
Questions buyers ask about this CAS
- What is the usual first-order route?
- A specification exchange, then a trial lot, then a commercial batch at the trial quantity before scaling. Each step is quoted, and none of them commits the customer to the next.
- Can we start with a trial quantity before a commercial order?
- Yes. A trial lot of (7Z,9E)-Dodeca-7,9-dienyl acetate is quoted separately from a production lot, because the packing and the analytical package differ. The sample carries the same documentation as a production lot, so the certificate you approve is the format you will receive at volume.
- What does the certificate of analysis report for this material?
- Identity, assay and isomeric ratio, each against a named method. (7Z,9E)-Dodeca-7,9-dienyl acetate is released against that certificate rather than against a catalogue description, and the lot number on the document matches the container.
- Can the packing be changed from 1kg / 25kg / 100kg?
- Usually, where the order supports it. Smaller fills are quoted with the packing cost shown separately, and customer-labelled units are handled as part of the order rather than as an exception afterwards.
Handling and storage
Close the container after dispensing, keep it clear of ignition sources, and follow the SDS for storage and disposal.
