Application

Sodium citrate tribasic dihydrate can be used as a catalyst to synthesize:     
  • Fused O- and N-heterocyclic derivatives via multicomponent Knoevenagel-cyclocondensation of isatin/aldehyde/ acenaphthylene-1,2-dione, malononitrile, and various C−H activated acids.     
  • Chromeno[3′,4′:5,6]pyrano[2,3-d]pyrimidines by the condensation reaction of 4-hydroxycoumarin, aromatic aldehydes, and barbituric acid/thiobarbituric acid.

It can also be used as:      
A reducing agent to synthesize metal nanoparticles via sol-gel method using corresponding metal salt precursors.    
A controlling agent in the synthesis of single-crystal of coordination polymer [Co(H2O)2Ni(CN)4 4H2O].

Complex coacervation is an emerging liquid/liquid phase separation (LLPS) phenomenon that behaves as a membrane-less organelle in living cells. Yet while one of the critical factors for complex coacervation is temperature, little analysis and research has been devoted to the
