  • Applications

    7-Methyl-3-methylene-1-octanol (CAS 57197-03-2) is a branched, unsaturated primary alcohol; the combination of a polar -OH and a hydrophobic tail makes it valuable as: (i) a versatile intermediate in synthesis, with the exocyclic double bond enabling epoxidation, hydroboration-oxidation to diols, ozonolysis or (cross-)metathesis for chain editing, while the -OH allows esterification, urethane formation, and ethoxylation; (ii) a precursor to esters, acetals, and carbonates explored in fragrance and flavor applications, structure-odor studies, and longevity tuning (branched aliphatic esters from this alcohol are routinely screened); (iii) a building block in pharma/agro routes where selective transformations around the alkene/hydroxyl give access to epoxy alcohols, 1,3-diols, and corresponding aldehydes/acids; (iv) a source for surfactants, lubricants, and materials additives via fatty-acid esterification (lubricant esters), polyoxyalkylation (nonionic surfactants), or acrylate/epoxy derivatization for use as reactive diluents in UV-curable coatings and adhesives; (v) an analytical reference/standard for GC-MS in VOC research and a model substrate for evaluating catalytic hydrofunctionalization, isomerization, or selective oxidation; actual use depends on purity, safety profile, and regulatory acceptance in each sector.
