Introduction (Ascorbic acid CAS No. 50-81-7 )
Vitamin C, also known as Ascorbic acid, is a polyhydroxyl compound with the chemical formula C6H8O6. The structure is similar to glucose, and the two adjacent enol hydroxyl groups on the second and third positions of its molecules are easily dissociated and H+ is released, so it has the property of acid, also known as L-ascorbic acid.
