Uses

DL-Methionine sulfoxide is used as pharmaceutical intermediates.

Definition

ChEBI: The S-oxide derivative of methionine. It is a biomarker of oxidative stress.

General Description

DL-Methionine sulfoxide is an oxidation product of DL-methionine.

Purification Methods

Likely impurities are dl-methionine sulfone and dl-methionine. Crystallise the sulfoxide by dissolving it in hot H2O and adding excess EtOH. [Lepp & Dunn Biochemical Preparations 4 80 1955, Micheel & Schmitz Chem Ber 72 518 1939, Beilstein 4 III 1650, 4 IV 3192.]
