Description

D-Erythrulose is a natural ketose sugar and a key intermediate in carbohydrate metabolism. This high-purity compound is valued for its unique reactivity and role as a building block in fine chemical synthesis. It serves as a critical raw material for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries, particularly for applications requiring a high degree of stereochemical control.

Application

• Cosmetic & Personal Care: Primary use as the active self-tanning agent in sunless tanning formulations (DHA-free or in combination with Dihydroxyacetone).
• Pharmaceutical Intermediates: Serves as a chiral building block for the synthesis of complex molecules, including antiviral and antibiotic drugs.
• Biochemical Research: Used as a substrate in enzymatic studies and metabolic pathway analysis within carbohydrate chemistry.
• Food & Flavor Industry: Acts as a precursor for natural flavor compounds and Maillard reaction intermediates.
• Specialty Chemicals: Employed in the production of surfactants, chelating agents, and other functional materials derived from renewable resources.
