Specification

Thiourea (CAS NO.62-56-6) is also named as 2-Thiopseudourea ; 2-Thiourea ; AI3-03582 ; CCRIS 588 ; Caswell No. 855 ; EPA Pesticide Chemical Code 080201 ; HSDB 1401 ; Isothiourea ; NSC 5033 ; Pseudothiourea ; Pseudourea, 2-thio- ; RCRA waste number U219 ; Sulourea ; THU ; Thiocarbamide ; Thiocarbonic acid diamide ; Thiomocovina ; Thiomocovina [Czech] ; Thiuronium ; Tsizp 34 ; USAF EK-497 ; Urea, 2-thio- ; Urea, thio- ; beta-Thiopseudourea . Thiourea (CAS NO.62-56-6) is white crystals or powder . It is water soluble. Thiourea is toxic and carcinogenic. When heated to decomposition Thiourea emits very toxic fumes of oxides of sulfur and oxides of nitrogen. Violent exothermic polymerization reaction with acrylaldehyde (acrolein), violent decomposition of the reaction product with hydrogen peroxide and nitric acid , spontaneous explosion upon grinding with potassium chlorate. Poisonous inhaled or swallowed. Irritating to skin; may cause allergic skin eruptions.
