Description

L-(+)-Erythrose is a vital four-carbon monosaccharide and a key intermediate in carbohydrate chemistry and metabolic pathways. Its high purity and defined stereochemistry make it an essential building block for the synthesis of complex sugars, nucleosides, and various bioactive compounds. This product is critical for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical industries who require reliable, high-quality chiral starting materials.

Application

• Pharmaceutical Intermediate: Serves as a crucial chiral precursor in the synthesis of antiviral drugs, antibiotics, and other active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a standard and substrate in enzymatic studies, metabolic pathway analysis (e.g., pentose phosphate pathway), and glycobiology research.
• Carbohydrate Chemistry: Acts as a fundamental building block for the chemical and enzymatic synthesis of oligosaccharides, glycoconjugates, and sugar analogs.
• Fine Chemical Synthesis: Employed in the production of specialty chemicals, flavors, and fragrances that require specific sugar-derived chirality.
• Diagnostic Reagents: Utilized in the formulation of reagents for clinical diagnostics and biosensors.
