5521-38-0, 2-(4-(4-Nitrophenyl)piperazin-1-yl)ethanol is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,5521-38-0

Step: 3A-2Synthesis of 2-[4-(4-Amino-phenyl)-piperazin-l-yl]-ethanol.Procedure:Pd-C (0.3g) was added to a solution of 2-[4-(4-Nitro-phenyl)-piperazin-l-yl]-ethanol (3g, 0.01195mol) in MeOH (20ml) and hydrogenated for 2hrs. The reaction was monitored by the TLC (20% MeOH: CHC13). The resultant was filtered, washed with MeOH and concentrated to afford 1.8g (69% yield) of 2-[4-(4-Amino-phenyl)-piperazin-l-yl]-ethanol as a pink solid.

As the paragraph descriping shows that 5521-38-0 is playing an increasingly important role.
