L-Altrose(CAS: 1949-88-8)

L-Altrose is a five-carbon sugar with the molecular formula C5H10O5. It crystallizes in prismatic or acicular form. The molecular weight is approximately 150.14 g/mol. L-Altrose is moderately soluble in water but insoluble in ethanol. It is less reactive compared to glucose, showing limited reducing properties.

L-Altrose is typically synthesized by the reduction of D-gluconolactone using hydrogen in the presence of a catalyst like rhodium. The process involves high selectivity and yield, often reaching over 95% purity. Other methods include bioconversion from other sugars or chemical synthesis routes.

L-Altrose is utilized in the pharmaceutical industry for the production of certain drugs and in the food industry as an alternative sweetener. It is also used in the production of polymers, sensors, and as a reducing agent in semiconductor manufacturing. Its use in biotechnology and enzyme engineering is also expanding.

Proper handling of L-Altrose requires wearing personal protective equipment such as gloves and safety goggles. It should be stored in a cool, dry place away from direct sunlight and heat sources. In case of a spill, ensure the area is well-ventilated and use appropriate cleaning agents. Always refer to the Safety Data Sheet (SDS) for detailed safety information.
