  • Applications

    Alaskene (CAS 28400-12-6) is commonly applied as an intermediate in catalytic synthesis (hydroformylation to aldehydes/alcohols used as plasticizer precursors, epoxidation for coatings, hydrosilylation to silicone derivatives, metathesis and oligomerization to polyalphaolefin lubricant base stocks), as a nonpolar solvent/carrier for hydrophobic actives and low-odor reaction media, as a reference and calibration material in gas chromatography for retention index methods, and as a volatility/viscosity tuner in coatings, inks, adhesives, and sealants; it also serves as a blending component or feedstock in lubricants and metalworking fluids to improve low-temperature flow, viscosity index, and volatility; in materials science it is used as a hydrophobic matrix for surface-energy studies and as a model substrate for subsequent functionalization, and in environmental research to probe oxidation and biodegradation—users should match purity grade to the end use and manage stability, since alkenes can oxidize or polymerize under harsh conditions.
