| S-Methyl-L-cysteine Usage And Synthesis |
| Chemical Properties |
white to light beige fine crystalline powder |
| Definition |
ChEBI: A cysteine derivative that is L-cysteine in which the hydrogen attached to the sulfur is replaced by a methyl group. |
| Purification Methods |
Likely impurities are cysteine and S-methyl-dl-cysteine. Crystallise it from H2O by adding 4volumes of EtOH. It also crystallises from MeOH with m 234-236o(dec), but after sublimation i t has m 267-270o and [] 27D -31.6o (c 1, H2O). [Rinderknecht et al.
