WebTCEP-HCl is pure, crystalline Tris (2-carboxyethyl)phosphine hydrochloride, a thiol-free compound that is highly effective at reducing protein and peptide disulfide bonds, as well as being odorless and stable. TCEP selectively and completely reduces even the most stable water-soluble alkyl disulfides over a wide pH range. 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 unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4). With traces of P2H4 present, PH3 is spontaneously flammable in air ( bitesize building the pyramids
