Description

D-(+)-Sorbose is a naturally occurring ketohexose sugar, a key intermediate in the commercial synthesis of ascorbic acid (Vitamin C). Its high purity and defined stereochemistry make it a critical building block for fine chemical and pharmaceutical manufacturing. This product is essential for research and production in the nutraceutical, food science, and biochemical synthesis sectors, where precise chiral starting materials are required.

Application

• Vitamin C Synthesis: The primary industrial application as a key chiral precursor in the Reichstein-Grüssner process for L-ascorbic acid production.
• Biochemical Research: Used as a carbon source in microbial culture media and as a substrate for studying enzyme specificity and carbohydrate metabolism.
• Chiral Building Block: Utilized in the synthesis of complex organic molecules, pharmaceuticals, and specialty chemicals where its specific stereochemistry is leveraged.
• Diagnostic Reagents: A component in certain clinical diagnostic kits and reagents for detecting specific enzymatic activities.
