  • Applications

    2-(1-Hydroxypropyl)furan (CAS 4208-61-1) is used mainly as a fragrance and flavor intermediate and as a versatile chiral building block in chemical synthesis; in real-world applications, it may serve as an odorant or scent ingredient in perfumery and personal care products, as a precursor for flavor compounds, and as a synthetic intermediate for pharmaceutical research. It is also evaluated for use in polymer and coating chemistries, where it can act as a reactive intermediate or co-monomer for specialty polymers and durable resins, and may appear in cosmetic formulations as a fragrance component or functional additive. Subject to local regulations and formulation limits.
