Glycolaldehyde dimethyl acetal

Glycolaldehyde dimethyl acetal (CAS 30934-97-5) is an aldehyde used as a semiochemical component in lures, release-rate trials and reference work.

No target species is recorded against this material in our file, so it is catalogued as a blend component and reference material. If a specification needs species named, send the target and we will confirm whether this isomer is the right starting point.

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

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.
