| Hazard Information | Back Directory | [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. | [reaction suitability]
reaction type: solution phase peptide synthesis | [storage]
Store at -20°C | [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.] |
