| | 4-Nitrobenzyl alcohol Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powde | | Uses | 4-nitrobenzyl alcohol is used as the sole source of carbon and nitrogen to study the pathway for the catabolism of 4-nitrotoluene by Pseudomonas. | | Uses | 4-Nitrobenzenemethanol is a potential building block in the synthesis of various pharmaceuticals. | | Definition | ChEBI: 4-nitrobenzyl alcohol is a member of the class of benzyl alcohols that is benzyl alcohol substituted at the para-position by a nitro group. It has a role as a xenobiotic metabolite. It is a member of benzyl alcohols and a C-nitro compound. | | Reactions | 4-Nitrobenzyl alcohol (200 mmol) was hydrogenated over 1.0 g 10% palladium on carbon (50% water) in 500 ml methyl t-butyl ether.

The synthesis method takes p-nitrobenzyl chloride (or bromine) as a raw material and water as a solvent, and obtains a white product, i.e. the 4-Nitrobenzyl alcohol through heating hydrolysis, cooling crystallization under the catalysis of imidazole type ionic liquid.
| | 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.] |
