Poly(methyl hydrogen siloxane) para síntese, Sigma-Aldrich®

Fornecedor: Merck

Descrição: Poly(methyl hydrogen siloxane) para síntese, Sigma-Aldrich®

MSDS

Capillary columns, traditional phases, SPB-1, Supelco®

Fornecedor: Merck

Descrição: These non-polar methyl silicone bonded poly(dimethyl siloxane) columns are used to separate the sample components according to boiling point.

Poly(methylhydrosiloxane) trimethylsilyl terminated

Fornecedor: Thermo Fisher Scientific

Descrição: Poly(methylhydrosiloxane) trimethylsilyl terminated

MSDS

Poly(methylhydrosiloxane)

Fornecedor: Thermo Fisher Scientific

Descrição: 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

Fornecedor: SIGMA ALDRICH MICROSCOPY

Descrição: 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.

Hydrogen fluoride pyridine complex (∼70% HF)

Fornecedor: Thermo Fisher Scientific

Descrição: Hydrogen fluoride pyridine complex (∼70% HF)
