Propionaldehyde

[3] Propionaldehyde exhibits the reactions characteristic of alkyl aldehydes, e.g. hydrogenation, aldol condensations, oxidations, etc.Rising demand for non-chlorocarbon solvents has caused some manufacturers to substitutively brominate n‑propanol to propyl bromide.However, the majority of applications use n‑propanol proper in esters or glycol ethers, or as a gentle alkylant for primary and secondary amines.[6] Propionaldehyde along with acrolein has been detected in the molecular cloud Sagittarius B2 near the center of the Milky Way Galaxy, about 26,000 light years from Earth.[10][11][12] With an LD50 of 1690 mg/kg (oral),[2] propionaldehyde exhibits low acute toxicity, but is a lung and eye irritant and is a combustible liquid.

E.g. chloroform Flammability 3: Liquids and solids that can be ignited under almost all ambient temperature conditions. Flash point between 23 and 38 °C (73 and 100 °F). E.g. gasoline Instability 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorus Special hazards (white): no code
