N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide. It is used in the petrochemical and plastics industries as a solvent, exploiting its nonvolatility and ability to dissolve diverse materials.
NMP is used to recover certain hydrocarbons generated in the processing of petrochemicals, such as the recovery of 1,3-butadiene and acetylene. It is used to absorb hydrogen sulfide from sour gas and hydrodesulfurization facilities. Due to its good solvency properties NMP is used to dissolve a wide range of polymers. It is also used as a solvent for surface treatment of textiles, resins, and metal coated plastics or as a paint stripper. It is utilized as a solvent in the commercial preparation of polyphenylene sulfide. In the pharmaceutical industry, N-methyl-2-pyrrolidone is used in the formulation for drugs by both oral and transdermal delivery routes.^[2] It is also used heavily in lithium ion battery fabrication, as a solvent for electrode preparation, though there is much effort to replace it with solvents of less environmental concern, like water.

DABCO or 1,4-diazabicyclo[2.2.2]octane is a chemical compound and a registered trademark for Air Products'' catalyst product line including 1,4-diazabicyclo[2.2.2]octane. It is a polyurethane catalyst, Baylis-Hillman reaction catalyst, complexing ligand, and Lewis base.[2] It is used to regulate the reaction rate in Flexplay time-limited DVDs by adjusting pH. Antioxidants, like DABCO, are used to improve the lifetime of dyes. This makes DABCO useful in dye lasers and in mounting samples for fluorescence microscopy (when used with glycerol and PBS).[3] DABCO can also be used to demethylate quaternary ammonium salts by heating in dimethylformamide (DMF).[4]Although the first pKa is 8.8 that is almost the same as ordinary alkylamines, the nucleophilicity is high because the alkyl groups does not disturb the lone pairs.DABCO has been used as a catalyst for a metal-free Sonogashira coupling, with or without microwave enhancement.[5] For example, phenylacetylene couples with electron-deficient iodoarenes to furnish the Sonogashira product in 77% yield with 95% selectivity.

Hydroxyethylmethacrylate or HEMA is the monomer that is used to make the polymer polyhydroxyethylmethacrylate. The polymer is hydrophobic; however, when the polymer is subjected to water it will swell due to the molecule's hydrophilic pendant group. Depending on the physical and chemical structure of the polymer, it is capable of absorbing from 10 to 600% water relative to the dry weight. Because of this property, it was one of the first materials to be successfully used in the manufacture of flexible contact lenses
