Definition

ChEBI: 2,6-Dichlorophenolindophenol sodium salt is an organic molecular entity.

Purification Methods

Dissolve it in 0.001M phosphate buffer, pH 7.5 (alternatively, about 2g of the dye is dissolved in 80mL of M HCl), and extracted into diethyl ether. The extract is washed with water, extracted with aqueous 2% NaHCO3, and the sodium salt of the dye is precipitated by adding NaCl (30g/100mL of NaHCO3 solution), then filtered off, washed with dilute NaCl solution and dried. It has max at 605nm. [Hiromi et al. Anal Biochem 101 421 1980.] The acetate M 310.1 has m 101-103o (from Et2O/pet ether) and 99.5-100.5o (from Et2O). [Beilstein 13 IV 1078-1079.]
