872-50-4 - Properties:

1-Methyl-2-Pyrrolidone (NMP) (CAS: 872-50-4), Colorless transparent liquid, it has strong water absorption. It can almost dissolve in all the solvents(ethanol, aldehyde, ketone, aromatic hydrocarbon, etc).

872-50-4 - Application:

1-Methyl-2-Pyrrolidone (NMP) (CAS: 872-50-4) is a high boiling, polar aprotic, low viscosity liquid. NMP has a good solvency for a wide range of organic and inorganic compounds and it is miscible with water at all temperatures and has a high chemical and thermal stability. It is used as a solvent for engineering polymers and coating resins.
Additionally,the polar nature and the low surface tension of NMP makes it an excellent cleaning medium and paint stripping solvent.
Widely used in aromatics extraction, the purification of acetylene, olefin and diolefin polyvinylidene fluoride solvent, auxiliary material of lithium ion battery electrodes, synthetic gas desulfurization and refined lubricating oil,lubricating oil, antifreeze, olefin extractant,refractory engineering plastic polymerization solvent, agricultural herbicides, insulation materials, integrated circuit production,Semiconductor industry precision instruments,circuit board cleaning,PVC tail gas recovery, cleaning agent, dye additives, dispersants, etc.It is also used as a solvent for polymers and as a medium for polymerization reactions,such as engineering plastics and aramid fibers.Also can be used in pesticide, medicine and detergent and so on.
Micro-electronic grade: Liguid crystal display,Semiconductor, circuit boards, carbon nanotubes and other high-end microelectronic industry.
Electronic grade: It is applicable to such industries as aramid fiber, ultrafiltration membrane, OLED plate photoetching, glue etching and other industries.
Battery grade:It is applicable to lithium batteries and other industries.
Pharmaceutical grade: Mainly used in pharmaceutical solvents, intermediates, etc
Industry grade: Mainly used in petroleum extraction, pesticides, insulating paint, industrial cleaning, etc.

872-50-4 - Storage:

1-Methyl-2-Pyrrolidone (NMP) (CAS: 872-50-4) is hygroscopic (picks up moisture) but stable under normal conditions. It will violently react with strong oxidizers such as hydrogen peroxide, nitric acid, sulfuric acid, etc. The primary decomposition products produce carbon monoxide and nitrogen oxide fumes. Excessive exposure or spillage should be avoided as a matter of good practice. Wearing butyl gloves when using 1-Methyl-2-Pyrrolidone. Please review MSDS prior to handling.

872-50-4 - Health Hazard:

Inhalation of hot vapors can irritate nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes causes irritation. Repeated and prolonged skin contact produces a mild, transient irritation.   

872-50-4 - Safety Profile:

Poison by intravenous route. Moderately toxic by ingestion and intraperitoneal routes. Mildly toxic by skin contact. An experimental teratogen. Experimental reproductive effects. Mutation data reported. Combustible when exposed to heat, open flame, or powerful oxidizers. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.
