2,3:4,5-di-O-isopropylidene-D-*arabinitol

Description:

2,3:4,5-di-O-isopropylidene-D-arabinitol is a carbohydrate derivative characterized by the presence of two isopropylidene protecting groups on the hydroxyl functionalities of D-arabinitol. This compound is typically used in organic synthesis and carbohydrate chemistry due to its ability to protect hydroxyl groups, facilitating further chemical transformations. The isopropylidene groups enhance the stability of the molecule and improve its solubility in organic solvents. The structure of 2,3:4,5-di-O-isopropylidene-D-arabinitol allows for selective reactions at specific sites, making it a valuable intermediate in the synthesis of more complex carbohydrates or related compounds. It is generally a white to off-white crystalline solid, and its reactivity can be influenced by the presence of the protecting groups, which can be removed under acidic or basic conditions when necessary. As with many organic compounds, proper handling and storage are essential to maintain its integrity and prevent degradation.
