4-Nitrobenzyl alcohol Usage And Synthesis

Chemical Properties	white to light yellow crystal powde
Uses	4-Nitrobenzenemethanol is a potential building block in the synthesis of various pharmaceuticals.
Definition	ChEBI: A member of the class of benzyl alcohols that is benzyl alcohol substituted at the para-position by a nitro group.
Synthesis Reference(s)	Organic Syntheses, Coll. Vol. 3, p. 652, 1955 The Journal of Organic Chemistry, 55, p. 2968, 1990 DOI: 10.1021/jo00296a078 Tetrahedron Letters, 19, p. 4985, 1978
Purification Methods	Crystallise the alcohol from EtOH and sublime it in vacuo. Purity should be at least 99.5%. Sublimed samples should be stored in the dark over anhydrous CaSO4 (Drierite). If the IR contains OH bands, then the sample should be resublimed before use. [Mohammed & Kosower J Am Chem Soc 93 2709 1979, Beilstein 6 IV 2611.]
