(Z)-9-Hexadecen-1-ol acetate

(Z)-9-Hexadecen-1-ol acetate (CAS 34010-20-3) is a C16 acetate ester used as a semiochemical component in surveillance and IPM work against Bertha armyworm and other species.

Our file records 2 targets for this material — Bertha armyworm (Mamestra configurata); Rice green caterpillar (Naranga aenescens) — spanning other taxa. That is why it is held for surveillance and programme work rather than as general stock.

Buyers take it as a blend building block for a defined pest complex, with the loading and dispenser chosen for the flight period and for the trap design already in use in the stand.

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

Acetates hydrolyse slowly in the presence of moisture and are the class most disturbed by warm storage. Lot history — how the material has been held since manufacture — matters more than the headline assay.

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

Documentation is lot-based: certificate of analysis, GC trace and safety data sheet travel with the consignment, and an isomer-ratio statement can be added where a specification calls for it.

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.

Target species recorded against this compound

• Bertha armyworm Mamestra configurata
• Rice green caterpillar Naranga aenescens

Species records are drawn from the blend literature filed for this material. Where a programme targets a species not listed, the blend is usually a ratio question rather than a different compound — send the target and we will confirm.
