Polimetilidrossilossano trimethylsilyl terminated

Fornitore: Thermo Scientific

Descrizione: Polimetilidrossilossano trimethylsilyl terminated

MSDS

Polimetilidrossilossano

Fornitore: Thermo Scientific

Descrizione: Poly(methylhydrosiloxane) is used in the reduction of esters to alcohols, catalyzed by a combination of titanocene dichloride and either n-BuLi or EtMgBr. It is a safer alternative to triethoxysilane, B22063, for reduction of phosphine oxides to phosphines, catalyzed by Ti(O-i-Pr)4. It is also used in greener amine synthesis by reductive amination as an alternative to borohydrides.

Poly-L-lysine hydrobromide

Fornitore: SIGMA-ALDRICH MICROSCOPY

Descrizione: Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.

Acqua ≥99.9%, HiPerSolv CHROMANORM®, PFAS grade per LC-MS

Codice catalogo: (92499.320)

Fornitore: VWR Chemicals

Codice articolo locale: VWRC92499.320

Descrizione: VWR® PFAS grade LC-MS solvents undergo a rigorous use test to ensure suitability for analysis of poly- and perfluoroalkyl substances resulting in an ultra low background of PFAS analytes. Using complementary methods a broad range of PFAS analytes are quantified to their detection limits by LC-MS.
