Product Description:

4-Methoxybenzaldehyde, also known as p-anisaldehyde, is an aromatic aldehyde characterized by a benzene ring substituted with a formyl group and a methoxy group at the para position. It is a colorless to pale yellow liquid with a characteristic sweet, floral, and slightly anise-like odor. Its primary industrial application is as a key fragrance ingredient and flavoring agent. It is widely used in perfumery for creating floral, hawthorn, and lilac notes, and in the food industry as a flavor additive. Beyond its organoleptic uses, p-anisaldehyde serves as a versatile and common synthetic building block in organic chemistry. It is frequently employed in the synthesis of various fine chemicals, pharmaceuticals (e.g., antihypertensive drugs), and agrochemicals through reactions such as aldol condensations, Grignard reactions, and reductive amination. The compound is also utilized as a derivatization agent in analytical chemistry for thin-layer chromatography (TLC) visualization of sugars and other compounds. It requires careful handling as it can cause skin and eye irritation.
