2,6-TNS Usage And Synthesis

Chemical Properties

off-white powder

Uses

Fluorescent probe for protein conformation studies.

Purification Methods

Crystallise the acid twice from 2% aqueous KOH and dry it under high vacuum for 4hours at room temperature. It also crystallises from H2O. It is tested for purity by TLC on silica gel with isopropanol as solvent. The free acid is obtained by acidifying a saturated aqueous solution. [Beilstein 14 H 762.]
