Molecular Formula: 
Molecular Structure: 
Molecular Weight: 
CAS No.: 



Erythorbic Acid occurs as white or slightly yellow crystals or powder. It gradually darkens when exposed to light. In the dry state, it is reasonably stable in air, but in solution, it rapidly deteriorates in the presence of air. It melts between164°C and 171°C with decomposition. One gram is soluble in about 2.5 mL of water and in about 20 mL of alcohol. It is slightly soluble in glycerin.



Erythorbic acid is an isomer of L-ascorbic acid, produced by the fermentations of microorganism. It is widely used in food industry and oral pharmaceutical formulations. In water solution, it reacts readily with atmospheric oxygen and other oxidizing agents, making it valuable as antioxidant. It is used to control oxidative color and flavor deterioration and generally regarded as nontoxic and nonirritant when used as an excipient. Erythorbic acid is readily metabolized and doesn’t affect the urinary excretion of ascorbic acid.
