Hoffer's Chlorosugar丨CAS 4330-21-6

Hoffer's chlorosugar is primarily used as a key intermediate in carbohydrate chemistry and glycoside synthesis. It serves as a versatile building block for preparing various protected sugar derivatives, glycosyl donors, and analogs in the synthesis of complex oligosaccharides, glycoconjugates, and natural products. The compound is widely employed in medicinal chemistry for designing carbohydrate-based drugs and vaccines, as well as in chemical biology to study carbohydrate–protein interactions. Additionally, it finds use in the preparation of stereochemically defined sugar molecules essential for enzymatic and synthetic applications.

Hoffer's chlorosugar offers high stereochemical control and reactivity, enabling selective glycosylation reactions under mild conditions. Its chlorinated functionality facilitates the formation of glycosidic bonds with excellent yield and regioselectivity. This intermediate simplifies the synthesis of complex sugars and glycoconjugates by reducing the number of protection/deprotection steps. Its use accelerates research in carbohydrate-based therapeutics and diagnostics by providing reliable access to structurally precise sugar building blocks.
