Appearance: | White or slightly yellow crystals or powder. On exposure to light it gradually darkens. Melts at about 190°C |
Solubility: | Freely soluble in water; spairingly soluble in alcohol; insoluble in chloroform, in ether, and in benzene. |
Identification A (By IR): | The IR spectra of the sample should be concomitant with the IR spectra of the corresponding standard. |
Identification B (By chemical test): | The solution should reduce slowly at room temperature but not more readily upon heating. |
