Molecular Formula: C9H15N3O2S CAS No.: 497-30-3 Appearance: White solid Solubility: Soluble in water Melting Point: 275-277ºC Molecular Weight: 229.299 Precise Mass: 229.088501 lb. Discovered in 1909, initially found in a fungus, the pure form is a white crystalline solid, water-soluble, and does not self-oxidize at physiological pH or in strongly alkaline solutions. It exists as two isomers, thiol and thione, which undergo tautomerism. At physiological pH, ergothioneine exists primarily as a thione, exhibiting a high standard redox potential. Compared to other thiols (glutathione, N-acetylcysteine, etc.) and even other antioxidants (ascorbic acid, tocopherol, etc.), ergothioneine is very stable and not prone to self-oxidation. A natural antioxidant, it protects cells, participates in DNA synthesis, and maintains cell growth and immune function. In Europe, America, Japan, and other countries and regions, its dosage forms include capsules, tablets, and powders. In contrast, the application of ergothioneine in my country is relatively limited. As a cosmetic ingredient, ergothioneine is mainly used in various skincare products and is not currently permitted for use in food.
