N,N-Bis(3-aminopropyl)methylamine Chemical Properties,Usage,Production

Uses

3,3′-Diamino-N-methyldipropylamine was used in the synthesis of:

• new bischromone derivatives, potential anticancer drugs
• polyamine derivatives containing dimeric quinolone, cinnoline and phthalimide moieties
• 3-(2,4-dinitroanilino)-3′-amino-N-methyldipropylamine

Flammability and Explosibility

Non flammable

Safety Profile

Poison by inhalation and skincontact. Moderately toxic by ingestion. A skin and severeeye irritant. Combustible whenexposed to heat or flame. To fight fire, use foam, fog, drychemical. When heated to decomposition it emits toxicfumes of NOx.
