| DL-Homocystine Usage And Synthesis |
| Chemical Properties | white to slightly beige solid | | Uses | DL-Homocystine is used in the synthesis of potential antitumor agents through inhibition of L-asparagine. There is growing clinical evidence that elevated homocysteine levels are associated with an increased risk of venous and arterial thrombosis. | | Purification Methods | dl-Homocystine crystallises in platelets from water with 1H2O and m 258-260o(dec), all operations should be carried out under N2.
