(9Z,12E)-9,12-Tetradecadien-1-ol acetate (CAS 30507-70-1): acetate ester for conjugated diene lures, packed to order with COA and SDS on every lot.
A fourteen-carbon dienyl acetate carrying both geometries in one molecule: (9Z,12E). Conjugated systems like this are the most active and the most fragile entries in a lure catalogue — they polymerise and oxidise faster than a saturated ester, and the E/Z split is part of identity rather than a quality parameter. Send the destination country with the enquiry — packing, labelling and paperwork depend on where the material is going.

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.
What changes between campaigns
Campaign production moves the batch size, not the specification. Where a route change is unavoidable it is disclosed before the lot ships, because a customer comparing two certificates should never have to guess why a number moved.
Isomeric form
Two lots can carry the same name and a different isomer distribution, which is why the release specification includes the ratio. This entry is the (9Z,12E) 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
Release over the life of a dispenser is a property of the whole formulation. Our part is to keep the input consistent enough that the dispenser behaves as designed.
Packing and lot size
The packing list is issued together with the COA, and both carry the lot number printed on the container.
Documentation
Material is supplied for professional and industrial use. The SDS goes with the shipment; the storage note below is a summary, not a replacement for it.
Ordering
Send the CAS number, the quantity, the packing and the destination. A written quotation follows within one business day.
Cross-contamination in a blending house
Two actives stored in the same cabinet share an atmosphere. Where both are the same class that is usually harmless; where one is a strong attractant used at a fraction of a percent, it is not.
What to send with an enquiry
If the quantity is still uncertain, send a range. A trial lot and a tonne are quoted differently, and both figures are more useful than a single number that will change.
From trial lot to production lot
Scale-up is where specifications tend to slip: the route changes, the isomer distribution moves with it, and the field result changes too. Keeping the release specification identical from trial to production lot, and comparing certificates rather than impressions, is the defence.
What the analytical package covers
If your QA department works to a monograph-style specification, say so at enquiry stage — parameters can be extended before a lot is released, but not added afterwards without re-analysis.
Release rate and dispenser matching
If catch falls away late in the season the usual cause is release rather than purity: the matrix has aged and the rate has dropped. Matching a fresh lot to the old specification keeps that variable out of the comparison.
Questions buyers ask about this CAS
- Do you supply outside species-specific moth lures?
- The same material is quoted for any application where the specification can be met. If the intended use has a documentation requirement attached to it, that is worth stating at enquiry stage so the paperwork can be planned in advance.
- 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 (9Z,12E)-9,12-Tetradecadien-1-ol 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. (9Z,12E)-9,12-Tetradecadien-1-ol acetate is released against that certificate rather than against a catalogue description, and the lot number on the document matches the container.
Handling and storage
Weighing is the usual point of contact: gloves and eye protection as listed in the SDS cover it.
