CAS: 104-09-6
Syringaldehyde, also known as 3,5-Dimethoxy-4-hydroxybenzaldehyde, is an aromatic aldehyde and a lignin degradation product. It is naturally occurring in various plants, including lilac (*Syringa vulgaris*), olive leaves, and vanilla beans. It appears as a white to light yellow crystalline powder or solid with a sweet, vanilla-like, woody, and phenolic aroma. Its molecular formula is C9H10O4 and its CAS number is 104-09-6.
Syringaldehyde is used as a flavoring agent in the food and beverage industry, contributing vanilla, woody, or spicy notes. In the fragrance industry, it is employed as an aroma ingredient in perfumes, cosmetics, soaps, and detergents.
Its applications primarily include its role as a fragrance component in various personal care products and household items, as a flavor enhancer or modifier in food formulations, and as a chemical intermediate in the synthesis of other organic compounds, pharmaceuticals, and specialty chemicals. It is also used in research related to lignin chemistry and plant metabolism.
Syringaldehyde is generally considered to have low toxicity. However, like many fine chemicals, it can be an irritant to the skin, eyes, and respiratory tract upon direct exposure. Inhalation of dust or prolonged skin contact should be avoided. Standard laboratory safety practices, including the use of personal protective equipment (gloves, eye protection) and good ventilation, are recommended during handling. It is harmful if swallowed in significant quantities.
