Piperonaldehyde Isosafrole Precursor
High-purity isosafrole marketed as a precursor for piperonal production is a separate chemically defined compound, classified under tariff item 2932.91.00. Its intended use does not affect classification, as the product is still isosafrole. It is used in the fragrance industry for synthesizing piperonal.
