Perillaldehyde is a colorless liquid at room temperature with a sweet, pleasant aroma. Its chemical formula is C10H16O, and its molecular weight is 152.23 g/mol. The compound is insoluble in water but soluble in alcohol and ether. It has a boiling point of 237 °C and a melting point of -2 °C.

Natural Occurrence

Perillaldehyde is found in the essential oil of perilla plants, which are native to East Asia. The compound is also present in smaller amounts in other plants, such as mint, citrus, and sage.

Uses

Perillaldehyde is used in the flavor and fragrance industry due to its sweet, pleasant aroma.
