(Z)-9-Tricosene (CAS 27519-02-4): pheromone active for lure and monitoring programmes, with the isomeric form and packing agreed per order and COA and SDS on every lot.
A long hydrocarbon chain with a single double bond and nothing to hydrolyse, (Z)-9-tricosene is one of the more forgiving actives in this catalogue to store and one of the less forgiving to formulate: it is strongly lipophilic, so the matrix holds it tightly and the dispenser, not the load rate alone, decides how much reaches the air. The parameters that matter to a QA department are the ones we keep stable between lots: identity, isomeric ratio and packing.

Chemistry of this entry
The structure drawing on this page is the whole molecule; the specification fixes what the drawing cannot show, which is the isomeric composition of the lot.
Stability in storage
Sealed, dark and cool is the general rule for this class. The SDS gives the temperature range and the incompatible materials for the specific compound.
What the analytics have to show
Identity, assay and the isomeric ratio, stated against a named method so your own laboratory can reproduce the numbers.
How the specification sheet is written
A usable specification sheet states identity, isomeric ratio, assay method and the packing units, and it names the parameters that will be checked on receipt. Ours is written so that your incoming inspection can repeat the same measurements rather than take the figures on trust.
Isomeric form
The stereodescriptor in the name is part of the specification rather than a naming habit. This entry is the (Z) 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
Load rate belongs to the formulator, but it only holds if the supplier can repeat the composition lot after lot, so we quote the variability with the material.
Packing and lot size
Standard packing is 1kg / 25kg / 100kg, and a different fill size is possible where the order justifies it. Every unit is labelled with lot number, net weight and the storage condition from the SDS.
Documentation
Every lot leaves with a certificate of analysis and a safety data sheet. The COA states assay, isomeric ratio and the method used, so the numbers can be checked rather than trusted.
Ordering
Send the CAS number, the quantity, the packing and the destination. A written quotation follows within one business day.
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.
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.
Questions buyers ask about this CAS
- Can we start with a trial quantity before a commercial order?
- Yes. A trial lot of (Z)-9-Tricosene 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. (Z)-9-Tricosene 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.
- How is the isomeric form fixed for CAS 27519-02-4?
- It is written into the release specification and reported on the certificate. Where the name already carries a stereodescriptor — as this one does — matching that descriptor is the first condition of the release.
Handling and storage
Store sealed and light-protected. The SDS gives the temperature range and the incompatible materials, and it is the controlling document.
