4-Amino-2-(Methylthio)Pyrimidine-5-Carbonitrile

EMERGENCY OVERVIEW 
Harmful by inhalation, in contact with skin and if swallowed.The toxicological properties of this material have not been fully investigated. 
Potential Health Effects 
Eye: 
May cause eye irritation. 
Skin: 
May cause skin irritation. Harmful if absorbed through the skin. 
Ingestion: 
Harmful if swallowed. May cause irritation of the digestive tract. 
The toxicological properties of this substance have not been fully investigated. Metabolism may release cyanide, which may result in headache, dizziness, weakness, collapse, unconsciousness and possible death. 
Inhalation: 
Harmful if inhaled. May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. May be metabolized to cyanide which in turns act by inhibiting cytochrome oxidase impairing cellular respiration. 
Chronic: 
Exposure to small amounts of cyanide compounds over long periods of time is reported to cause loss of appetite, headache, weakness, nausea, dizziness, and symptoms of irritation of the upper respiratory tract and eyes.

Section 4 - FIRST AID MEASURES
Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid. 
Skin: 
In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse. 
Ingestion: 
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid. 
Inhalation: 
Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
