N-Hydroxyphthalimide Chemical Properties,Uses,Production

Chemical Properties

yellow moist powder

Uses

Additive in to DCC method of peptide synthesis used to improve yield of optically pure product.

Uses

Catalyst for oxidation reactions.

Purification Methods

N -Hydroxyphthalimide [524-38-9] M 163.1, m 230o, ~235o(dec), 237-240o, 7.0. Dissolve the imide in H2O by adding Et3N to form the salt and while hot, acidify, cool and pour into a large volume of H2O. Filter off the solid, wash it with H2O and dry it over P2O5 in a vacuum. [Nefken & Teser J Am Chem Soc 83 1263 1961, Fieser 1 485 1976, Nefkens et al. Recl Trav Chim, Pays-Bas 81 683 1962] The O-acetyl derivative has m 178-180o (from EtOH). [Beilstein 21/11 V 100.]
