Product Name:S-Methyl-L-cysteine sulfoxide
English Name:S-Methyl-L-cysteine sulfoxide
CAS No.:6853-87-8
Aliases:Methiin, L-3-(Methylsulfinyl)alanine, 2-Amino-3-(methylsulfinyl)propanoic acid
Molecular Formula:C4H9NO3S
Physical Properties:White crystalline powder with a characteristic sulfurous odor; freely soluble in water, slightly soluble in ethanol, insoluble in diethyl ether; stable in air, may slightly discolor upon exposure to light; specific rotation [α]D20 ≈ -52° (c=1, H2O). Naturally occurring in Allium plants such as onions and garlic.
Uses:Mainly used as an organic synthesis intermediate for the preparation of cysteine derivatives. It serves as a standard reference for sulfur-containing flavor precursors in Allium plants in biochemical and food flavor research. It is also applied in metabolic studies of plant-derived sulfur compounds.
Technical Specifications:
Molecular weight: 151.18
Assay: ≥98% (HPLC)
Appearance: white crystalline powder
Melting point: 160-165°C (decomp.)
Solubility: freely soluble in water (50 mg/mL), slightly soluble in ethanol
