Some of their cas registry numbers are 13138-21-1 and 75849-83-1 CODEN: HTCYAM. ISSN: 0385-5414. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 45 A new synthesis of 5-amino-1,2,3-thiadiazole from diazoacetonitrile and H2S in the presence of a base is described. Diazoacetonitrile is undoubtedly explosive but with this method, the authors found it could be used for industrial purposes. .
