Other Safety InformationIMAP assessments - Quinolines: Human health tier II assessment
Fire HazardsThis compound is probably combustible. (NTP, 1992)
Health HazardsSYMPTOMS: Acute exposure to this compound will result in irritation to skin and mucous membranes.
Hazards SummaryA mild skin irritant; [RTECS] A skin and mucous membrane irritant; [NTP] A skin and strong eye irritant; Toxic by ingestion and skin absorption; [Alfa Aesar MSDS] See Quinoline.
Reactive GroupAmines, Phosphines, and Pyridines
Reactivity Profile
QUINALDINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides. Keep tightly closed and protected from light (NTP, 1992).
Air and Water ReactionsSlightly soluble in water.
Hazard Classes and Categories

Acute toxicity - category 4
Safety & protection
First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
