(±)-mandelic acid
benzeneacetic acid, a-hydroxy-
It is an isomer of cresotinic acid (2-hydroxy-3-methylbenzoic acid) and oxymethylbenzoic acid (2-methoxybenzoic acid). Derivatives of mandelic acid are formed as a result of metabolism of adrenaline and noradrenaline by monoamine oxidase and catechol-o-methyl transferase. It is also present in certain skin care products, is an intermediate molecule in the production of other biochemicals, may be used as an analytical reagent and is a precursor in the manufacture of dyes. Mandelic acid is an aromatic alpha hydroxy acid with the molecular formula C8H8O3. It is a white crystalline solid that is soluble in water and most common organic solvents. [HMDB]
