Questions And Answer | Back Directory | [?Synthesis]
Ethylamine thiourea is synthesized by using cycloethylamine, hydrobromic acid and thiourea as raw materials: firstly, thiourea is mixed with hydrogen bromide acid, and cycloethylamine is added dropwise at a temperature below 150 °C. After the reaction is completed, add activated carbon to filter, and then reduce Dehydration under pressure, crystals are precipitated when the temperature is below 50°C, filtered, and washed twice with absolute ethanol. |

Hazard Information | Back Directory | [Description]
S-(2-aminoethyl) Isothiourea is a non-selective inhibitor of all NOS isoforms. For human nNOS, eNOS, and iNOS, the Ki values are 1.8, 2.1, and 0.59 μM, respectively.1 | [Chemical Properties]
Crystals, hygroscopic. | [Uses]
NOS inhibitor | [Purification Methods]
Crystallise the salt from absolute EtOH/ethyl acetate or MeOH. Store dry as it is hygroscopic in a humid atmosphere. It is a radioprotective agent. When refluxed in EtOH for 16hours or H2O for 30minutes, it decomposes to 2-amino-4(5H)-thiazoline hydrobromide which on recrystallisation from isoPrOH/EtOAc has m 175-176o [Doherty et al.
