Applicazioni

3-Hydroxypropionitrile has been used as polar solvent to investigate the orientation of the phospholipid at the surface of the polar solvents by neutral impact collision ion scattering spectroscopy and as a reagent for carboxyl protection in peptide synthesis. It has been used also in solid state composite electrolyte for dye-sensitized solar cells.

Note

Stable under recommended storage conditions. Incompatible with oxidizing agents.

Protection of carboxylic acids as 2-cyanoethyl esters can be accomplished by DCC-DMAP coupling. The esters can be cleaved with TBAF in DMF-THF: Chem. Pharm. Bull., 42, 147 (1994), or Na2S in methanol: Chem. Pharm. Bull., 42, 1579 (1994).

Can also be used to protect the phosphate group, by condensation with 2,4,6-Triisopropyl­benzenesulfonyl­ chloride, A11458: Chem. Pharm. Bull., 25, 2844 (1977), or DCC: J. Am. Chem. Soc., 83, 159 (1961). Cleavage can be effected with an amine: Tetrahedron Lett., 23, 5119 (1982), ammonia: J. Org. Chem., 59, 2482 (1994); Tetrahedron Lett., 35, 4311 (1994), or TBAF: Tetrahedron Lett., 1255 (1976).
