  • Applications

    Isopiperitenol (CAS 491-05-4) is an allylic monoterpenoid alcohol in the mint biosynthetic pathway, used mainly as a synthetic intermediate toward isopiperitenone, pulegone, menthone and related derivatives; as a chiral building block in terpene chemistry; as a substrate and analytical reference for studies of limonene-3-hydroxylase and plant monoterpene metabolism; as a GC–MS/LC–MS/NMR reference when profiling essential-oil volatiles; and in flavor and fragrance R&D as an experimental ingredient or reaction model to design minty/herbal notes, while serving as a convenient precursor to value-added oxygenated monoterpenes for pharmaceutical, food-flavor, and personal-care applications.
