  • Applications

    (Z)-Tamarindienal (CAS 149575-43-9) is primarily considered as an aroma-chemical used in fragrance and flavor applications. It is commonly evaluated as a fragrance ingredient to impart tamarind- or tropical-fruity notes, and may serve as a flavor intermediate in formulated flavor systems. In cosmetics and personal care, it can be used as a fragrance component in products such as lotions, shampoos, and soaps. In household and cleaning products, it may function as an odorant to lend a fruity character. In industrial manufacturing, it can act as an intermediate or building block in fragrance and flavor synthesis, and it may be used as a fragrance modifier in polymers or plastics where odor contribution is desired. All usages are subject to local regulations and formulation limits.
