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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
