Consensus Reports

NCI Carcinogenesis Bioassay (feed); No Evidence: mouse, rat NCITR* National Cancer Institute Carcinogenesis Technical Report Series. (Bethesda, MD 20014) No. NCI-CG-TR-31 (1977). . Reported in EPA TSCA Inventory. EPA Genetic Toxicology Program.

Safety Profile

Moderately toxic by ingestion and several other routes. A human teratogen. Human reproductive effects by ingestion and possibly other routes: stillbirth, developmental abnormalities of the cardiovascular (circulatory) system and urogenital system, and unspecified neonatal effects. Human systemic effects by ingestion: nausea or vomiting, hypoglycemia. Other experimental teratogenic and reproductive effects. Mutation data reported. Implicated in aplastic anemia. When heated to decomposition it emits very toxic fumes of NO_x and SO_x.

Specification

The chemical synonyms of 1-Butyl-3-(4-methylphenyl)sulfonylurea (64-77-7) are Labotest-bb lt00772316 ; 3-[P-tolyl-4-sulfonyl]-1-butylurea ; 1-Butyl-3-(p-tolylsulfonyl)urea ; 1-Butyl-3-(4-methylbenzenesulfonyl)urea ; 1-Butyl-3-(4-methylphenylsulfonyl)urea ; 1-N-butyl-3-(p-tolylsulfonyl)urea ; Toluina ; Tolbutamide .Tolbutamide is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases. Imides are less basic yet and in fact react with strong bases to form salts. they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
