Product Description:

P-Tolualdehyde is an aromatic aldehyde with the chemical formula C8H8O. It is a colorless to pale yellow liquid with a characteristic almond-like odor. It is an important organic intermediate in chemical synthesis. Its primary industrial application is as a key raw material and intermediate in the synthesis of various fine chemicals. It is widely used in the production of pharmaceuticals, agrochemicals, and particularly in the fragrance and flavor industry. It serves as a building block for compounds like p-methylcinnamic acid and is a component in the synthesis of certain dyes and liquid crystal materials. Its almond-like aroma also makes it a direct ingredient in some fragrance formulations. As a versatile synthon, p-tolualdehyde undergoes typical reactions of aromatic aldehydes, such as condensation, oxidation, and reduction. It should be handled with care as it may cause skin and eye irritation.
