RTECS: WN3850000
HazardClass: 6.1
PackingGroup: III
HS Code: 29051900
HS Code: 29269095
Poison by ingestion, intraperitoneal, and subcutaneous routes. An experimental teratogen. Combustible when exposed to heat or flame. Decomposes exothermically above 195°C. Can react with oxidizing materials. To fight fire, use alcohol foam, CO₂, dry chemical. When heated to decomposition, or on contact with acid or acid fumes, it emits highly toxic fumes of NO_x and CN⁻. See also NITRILES.

Succinonitrile Standards and Recommendations

ACGIH TLV: CL 5 mg(CN)/m³ (skin)
NIOSH REL: (Nitriles) TWA 20 mg/m³

Succinonitrile Specification

Succinonitrile (CAS NO.110-61-2) is hazardous,so the first aid measures and others should be known .Such as:
Skin: Get medical aid. Should flush skin with plenty of water immediatelyfor at least 15 minutes while removing contaminated clothing and shoes.
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.Then get medical aid soon.
Inhalation: Remove from exposure and move to fresh air immediately.Give artificial respiration While not breathing. when breathing is difficult, give oxygen.And as soon as to get medical aid.
Ingestion: Wash mouth out with water,and get medical aid immediately.
Notes to Physician: Treat supportively and symptomatically.
Chemical Stability: Stable under normal pressures and temperatures.
Incompatibilities with Other Materials: Strong reducing agents, strong bases, strong acids,strong oxidizing agents.
Conditions to Avoid: Incompatible materials,moisture.
Hazardous Decomposition Products: Nitrogen,oxides of phosphorus, hydrogen iodide, oxides of nitrogen, carbon dioxide, carbon monoxide.
