  • Applications

    Recognized as a terpene diol, Terpin (CAS 565-48-0) is commonly employed as a fragrance and flavor intermediate, further converted to derivatives such as terpineol and aromatic esters for formulating perfumes, soaps, detergents, and deodorizing products; in traditional pharmaceuticals, terpin/terpin hydrate formulations have been used as expectorants to help relieve cough and nasal congestion (usage and approval vary by jurisdiction); in foods and beverages it may serve, where permitted, as a trace-level flavor modifier; in agrochemicals and household care it is used as a co-solvent, odor adjuster, and odor masker; in organic synthesis and R&D it functions as a building block for other terpene compounds, an analytical reference for terpene metabolism/oxidation studies, and a model substrate for pinene hydration; in practical use, note that odor profile depends on isomer ratio and purity, the material can oxidize over time affecting scent and stability, and users should follow safety guidance (avoid direct inhalation, may irritate skin/eyes) and comply with labeling and use limits specific to each sector.
