Chemical Product Description & Applications
3-Methyl-5-benzofuranol is a defined aromatic fragrance substance also named 3-methylbenzofuran-5-ol. Its molecular structure combines a benzofuran ring with a phenolic hydroxyl group and a methyl substituent. It is used as an odor-contributing material in fragrance compositions, providing a distinct component that can be balanced with other ingredients to construct the desired accord.
The concentrated substance is a solid at ordinary room temperature and has limited water solubility. It is dissolved in a compatible fragrance carrier to obtain uniform distribution before incorporation into finished products. Its relatively low volatility is relevant when balancing the persistence of a fragrance composition. The CAS identity is associated with the individual substance assessed under the marketing name Saffiano.
Typical Applications
- Fine-fragrance composition: Used as an individual odorant in fragrance concentrates for perfumes and related scented products. The perfumer balances its contribution with other aroma ingredients to create the intended composition.
- Personal and household fragrance compounds: Used in perfume mixtures that are subsequently incorporated into skin-care, rinse-off, air-care or household products. The fragrance compound provides the intermediate delivery format between the concentrated substance and the finished product base.
