SOx and NOx. | [Hazardous Substances Data]
541-53-7(Hazardous Substances Data) |
| Hazard Information | Back Directory | [General Description]
Crystalline solid. Used as a plasticizer, as a rubber accelerator, and as an intermediate in manufacturing of pesticides. | [Reactivity Profile]
DITHIOBIURET(541-53-7) is a thioamide, which may behave as a weak acid in solution and therefore will react with base foeming salts with production of heat. DITHIOBIURET(541-53-7) may react with acids and reducing agents to form toxic hydrogen sulfide gas. This may be vigorous depending on the nature of the reducing agent. Organic amides/imides react with azo and diazo compounds to generate toxic gases. The combustion of these compounds generates mixed oxides of nitrogen (NOx). | [Air & Water Reactions]
pH of the saturated aqueous solution is 5.8. | [Health Hazard]
The material is highly toxic. It may cause respiratory failure. | [Fire Hazard]
When heated to decomposition, DITHIOBIURET emits highly toxic fumes of oxides of sulfur and nitrogen. | [Description]
Dithiobiuret is a colorless, crystalline solid.Molecular weight= 135.22; Freezing/Melting point =(decomposition) 189℃. Hazard Identification (based onNFPA-704 M Rating System): Health 3, Flammability 1,Reactivity 0. Soluble in water; solubility 5 0.25 g/110 mLat 25℃ | [Uses]
Dithiobiuret is an intoxicant which causes ascending motor weakness when given chronically to rodents. | [Potential Exposure]
This material is used as a plasticizer,as a rubber accelerator; and as an intermediate inmanufacturing of pesticides | [First aid]
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. Keepvictim quiet and maintain normal body temperature. Effectsmay be delayed; keep victim under observation. | [storage]
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with dithiobiuret you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from oxidizers and reducing agents.Where possible, automatically pump liquid from drums orother storage containers to process containers. | [Shipping]
Pesticides, solid, toxic, n.o.s. have a labelrequirement of “POISONOUS/TOXIC MATERIALS.”They fall in Hazard Class 6.1 and this material in PackingGroup II |
