Anisaldehyde

Natural Anisaldehyde (Natural Anisic Aldehyde)

Natural p-Anisaldehyde (4-methoxybenzaldehyde) is a natural aromatic aldehyde obtained by selective oxidation and refining from star anise oil or natural anethole. It is a key secondary aroma component of star anise essential oil, featuring an intense, long-lasting hawthorn-floral and vanilla-sweet fragrance.
