Anwendungen

4-Methoxybenzaldehyde is widely utilized in the fragrance and flavor industry. It finds application as an important intermediate in the synthesis of other organic compounds, perfumes and pharmaceuticals like antihistamines. It is also used in the preparation of agrochemicals, dyes and plastic additives. A solution of para-anisaldehyde with acid and ethanol is used as stain in thin layer chromatography (TLC), which provides easy identification of different compounds.

Bemerkungen

Air and Light Sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong bases, strong oxidizing agents and strong reducing agents.
