Where it is used
- C12 linear epoxide; middle of the C6 to C14 series.
- Reactive diluent or monomer in epoxy and UV-cure systems, where viscosity and shrinkage are set by chain length
- Building block for ring-opening functionalisation with amines, alcohols and thiols
Reading the specification
The number that matters for an epoxide is not only assay but epoxide equivalent weight (EEW), calculated from molecular weight and functionality; dosing in a cure or a chain extension follows EEW, not mass. For this series, chain length controls the practical properties: shorter chains are more volatile and more reactive per gram, longer chains give lower shrinkage, better hydrophobicity and slower cure. Store sealed – epoxides ring-open in the presence of acid, base or water, and the resulting glycol shows up as a falling EEW.
Packaging and supply
Supplied in research quantities from 1 g and 5 g through 25 g and 100 g, with scale-up to bulk packed under nitrogen or argon where the product allows it. Every lot ships with a batch COA and the current SDS, FOB or CIF against destination. If you need a specific assay method, a water limit, an enantiomeric purity figure or a metal-residue limit, state it at enquiry stage – the batch documentation is issued against the specification you agree.
Handling: Use gloves, eye protection and local ventilation. Avoid dust generation, keep containers closed when not in use, and refer to the SDS for first aid, storage and disposal.
