(10E,12Z)-Hexadecadienal

(10E,12Z)-Hexadecadienal (CAS 63024-98-6) is a C16 aldehyde with a 10E,12Z double-bond geometry used as a semiochemical component in surveillance and IPM work against Silkworm. It is a defined isomer rather than a mixture, which is what a blend specification normally asks for.

The only target recorded in our file is Silkworm (Bombyx mori) — which is why the material is held for surveillance work rather than as general stock.

It is also used as a spiking standard when a laboratory needs to confirm that a finished lure still contains what the label claims after a season in the field.

Where it is used

This material sits in the working part of the catalogue: the compounds formulation teams ask for by CAS when a blend needs a specific isomer, a reference point for a chromatogram, or a small quantity to test before committing to a drum.

Isomer, stability and handling

Aldehydes are the most oxidation-sensitive class here. In practice the (E)/(Z) geometry of the double bond, not the headline assay figure, is what decides whether a blend behaves as the specification intends, so the isomer statement on the certificate is the number to read first.

Store cool, dry and dark: sealed under nitrogen or argon at −20 °C for holdings longer than one season, and let containers reach room temperature before opening so condensation does not enter the material. Weigh and formulate in a ventilated area; the safety data sheet gives handling detail for the neat substance.

Documentation and packing

Each delivery carries a certificate of analysis, a GC trace and an SDS. Where a tender asks for method detail, the chromatographic conditions are supplied separately on request.

Standard packing for this line is 1kg / 25kg / 100kg, with smaller development quantities available so a blend can be trialled before a bulk order. Lead time is confirmed at quotation.
