cuminaldehyde

Cuminaldehyde, also known as 4-isopropylbenzaldehyde, is an aromatic aldehyde that occurs naturally in cumin seeds. Its chemical formula is C10H12O and its molecular weight is about 148.20 g/mol. The structure features a benzene ring bearing an aldehyde group (benzaldehyde) with an isopropyl substituent at the para position.

Occurrence and production: Cuminaldehyde is a major constituent of the essential oil of Cuminum cyminum and contributes to cumin’s characteristic aroma and flavor. Industrially, it can be prepared by selective oxidation of compounds such as p-cymene, or produced synthetically from readily available aromatics. It can also be isolated from cumin oil by distillation and purification.

Applications: It is widely used as a flavoring agent in foods and beverages, imparting a warm, spicy note characteristic of cumin. In addition to culinary uses, cuminaldehyde finds use in perfumery and serves as an intermediate in organic synthesis for various pharmaceuticals, dyes, and fragrance compounds.

Safety and regulatory notes: Like many aldehydes, cuminaldehyde can be irritating to skin, eyes, and the respiratory tract. It should be handled with appropriate safety precautions, including protective equipment and adequate ventilation. In seasoning or cosmetic contexts, it is subject to applicable regulatory limits and purity requirements.
