Skin Corr. 1A | [Safety Profile]
Poison by
intraperitoneal and intravenous routes. This
material is strongly alkaline. Liquid and
vapors are corrosive to the skin, eyes, or
mucous membranes. A very dangerous fire
hazard; keep away from sparks, heat
sources, and powerful oxidizers. Keep in
closed containers. To fight fire, use alcohol
foam. When heated to decomposition it
emits highly toxic fumes of NOx. | [Toxicity]
LD50 orally in Rabbit: 280 mg/kg |
| Hazard Information | Back Directory | [Hazard]

CLEAR COLOURLESS LIQUID | [Uses]
A methylated pyrollidine which is an essential part of the structure of Cefipime (C242750) often analyzed via ion chromatography. A cigarette smoke constitutent. | [Preparation]
n-methylpyrrolidine was successfully synthesized in an aqueous medium by using methylamine and 1,4-dibromobutane in the presence of catalyst k2co3 at a moderated temperature. here, n-methylpyrrolidine was firstly synthesized via the green chemistry process, in which both the water solvent and potassium carbonate catalyst were inexpensive and environmentally friendly. also, the reaction temperature was quite moderated at 90°C.
green organic synthesis of n-methylpyrrolidine | [Flammability and Explosibility]
Highlyflammable | [Synthesis]
1-Methylpyrrolidine is prepared by hydrogenation of N-Methylpyrrole
over Adams' catalyst. | [storage]
Store at -20°C |
