  • Applications

    (-)-3-Butylphthalide (CAS 3413-15-8) is considered a fragrance-related chemical and can function as an odorant or a light fixative in perfumery and cosmetics. It is also evaluated as a chiral building block and a synthetic intermediate for the preparation of more complex phthalide-derived compounds in pharmaceutical and fine-chemical research. In industrial manufacturing, it may be used as an intermediate in the synthesis of specialty chemicals and aroma-related formulations.
