Description

D-(-)-Erythrose is a four-carbon monosaccharide (a tetrose) and a key intermediate in carbohydrate metabolism and synthesis. Its unique stereochemistry makes it a valuable chiral building block and precursor for the production of complex sugars, pharmaceuticals, and fine chemicals. This compound is essential for research and development in the pharmaceutical, biotechnology, and synthetic chemistry industries, where it serves as a starting material for nucleosides, antibiotics, and various bioactive molecules.

Application

• Pharmaceutical Synthesis: As a chiral precursor in the synthesis of nucleoside analogs, antiviral drugs, and other active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a substrate or intermediate in enzymatic studies, metabolic pathway analysis, and glycobiology research.
• Fine Chemical Production: Serves as a building block for the synthesis of complex carbohydrates, specialty sweeteners, and flavor compounds.
• Cosmetic & Personal Care: Potential use in the development of skin-conditioning agents and moisturizers due to its sugar-based structure.
• Food Science Research: Employed in studies related to Maillard reaction chemistry, caramelization, and the development of novel food ingredients.

Quality Control

Our D-(-)-Erythrose is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including identity confirmation by IR and NMR, purity assessment by HPLC, and specific tests for related substances and residual solvents. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect stability and purity.
