2-Methylpiperazine Usage And Synthesis
Chemical Properties
white to yellow crystalline powder and chunks
Uses
2-Methylpiperazine is used as a reagent in the design, synthesis and biological evaluation of diaminoquinazolines as b-catenine/Tcell transcription factor 4 (Tcf4) pathway inhibitor.
Purification Methods
Purify it by zone melting and by distillation. It is hygroscopic. The picrate has m 275-276o. [Beilstein 23 II 16, 23 III/IV 393, 23/3 V 267.]
