Methylgallic acid-O-sulphate

C8H8O8S (263.9939888)

Methylgallic acid-O-sulphate is a conjugate of methylgallic acid and sulphate. methylgallic acid is a methyl ester of gallic acid. Gallic acid is a trihydroxybenzoic acid, a type of phenolic acid, a type of organic acid, also known as 3,4,5-trihydroxybenzoic acid, found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. The chemical formula is C6H2(OH)3COOH. Gallic acid is found both free and as part of hydrolyzable tannins. (Wikipedia)
