Chemistry of Crosslinking Thermo Fisher Scientific - US
WebEDC crosslinking reactions must be performed in conditions devoid of extraneous carboxyls and amines. Acidic (pH 4.5 to 5.5) MES buffer (4-morpholino-ethane-sulfonic acid) is most effective, but phosphate buffers at pH ≤ 7.2 are also compatible with the reaction chemistry. Phosphines are compounds that include PH3 and the organophosphines, which are derived from PH3 by substituting one or more hydrogen atoms with organic groups. [4] They have the general formula PH3−nRn. Phosphanes are saturated phosphorus hydrides of the form PnHn+2, such as triphosphane. [5] See more Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly See more Philippe Gengembre (1764–1838), a student of Lavoisier, first obtained phosphine in 1783 by heating white phosphorus in … See more Phosphine may be prepared in a variety of ways. Industrially it can be made by the reaction of white phosphorus with sodium or potassium hydroxide, producing potassium or sodium hypophosphite as a by-product. 3 KOH + P4 + 3 H2O … See more Deaths have resulted from accidental exposure to fumigation materials containing aluminium phosphide or phosphine.
