화학적 성질
white to yellowish crystalline powder용도
2,2'-Dipyridyldisulfide, sometimes known as DPS, is used for preparing thiols and activating or protecting carboxylic acid with triphenylphosphine.일반 설명
2,2'-Dithiodipyridine is a nucleocapsid zinc finger targeting compound and can abrogate the infectivity of human immunodeficiency virus type-1 virions. It is a thiol reagent.Purification Methods
Recrystallise the disulfide H2O from *C6H6/pet ether (6:7), ligroin or *C6H6. The picrate has m 119o (from EtOH). [Walter et al. Justus Liebigs Ann Chem 695 7785 1966, Marckwald et al. Chem Ber 33 1556 1900, Brocklehurst & Little Biochem J 133 67,78 1973, Beilstein 21 III/IV 48.] It has been used as a 1mM solution in EtOH for the spectrophotometric estimation of thiols. Essentially the thiol displaces half the disulfide molecule liberating the 2-mercaptopyridine anion, thereby shifting the from 340nm (of the disulfide) to 268nm (of the anion) at pH 9, or 278nm in H2O.
