Fumaraldehyde bis(dimethyl acetal)（Cat No.:L000110）is a protected dialdehyde derivative of fumaraldehyde, where both aldehyde groups are masked as dimethyl acetals. This compound appears as a colorless liquid and is commonly used in organic synthesis as a stable equivalent of fumaraldehyde. The acetal groups provide protection against nucleophilic attack and oxidation, allowing for controlled reactivity in multistep synthetic routes. Upon acid-catalyzed hydrolysis, it regenerates the free aldehyde functionalities. It is particularly useful in polymer chemistry, heterocycle formation, and as a building block in pharmaceutical and fine chemical development.
