Derivative Type: Trihydrate
Molecular Formula: C5H10NNaS2.3H2O
Molecular Weight: 225.31
Percent Composition: C 26.65%, H 7.16%, N 6.22%, Na 10.20%, S 28.46%, O 21.30%
Properties: Thin, irregular plate-like crystals from acetone, mp 94-102°. Also reported as 90-92° (Sunderman, Sunderman). Freely sol in water; sol in ethanol, methanol, acetone. Insol in ether, benzene. The aq soln is alkaline to litmus and phenolphthalein and slowly dec. (pH of 10% aq soln is 11.6 at room temp). The addition of an acid to the aq soln produces a white turbidity due to the liberation of carbon disulfide. uv max (ethanol): 257, 290 nm (e 1200, 13000). LD50 orally in rats, mice: 2830, 1870 mg/kg; i.v. in mice: >1000 mg/kg (Renoux, 1982).
