Quotation within one business day. COA and SDS with every lot.
4-Pentynoic acid, methyl ester (CAS 21565-82-2): pheromone active for lure and monitoring programmes, packed to order with COA and SDS on every lot.
CAS 21565-82-2 is a semiochemical: one carbons, one double bond, at C4. The name fixes no stereodescriptor; the release certificate fixes the rest. Every figure below is a commitment we can document; anything that depends on your formulation is marked as such.

Isomeric form
For a blend already on the market, the isomer ratio is the first thing to match and the last thing anyone documents. We document it. This name carries no stereodescriptor, so the isomeric composition is fixed by the release specification rather than by the title, and it is reported 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.
Documentation
Confidentiality runs both ways: customer blends are not disclosed, and we do not ask for more of a formulation than the specification requires.
Handling and storage
Keep the container closed and out of direct light, away from heat, and handle it with the protection named in the SDS.
