3-(1-Pyridinio)-1-propanesulfonate химические свойства, назначение, производство
Описание
3-(1-Pyridinio)-1-propanesulfonate is a white crystalline powder used to prepare electroplating additives.It has good thermal qualitative and chemical stability, and its mechanical strength is also very good. The low polymer molecular weight is prone to disproportionation and cross-linking reactions.Химические свойства
White to Off-White Solid.Использование
3-(1-Pyridinio)-1-propanesulfonate can be used:- As a Bronsted acid ionic liquid catalyst in combination with H2SO4 and H3PO4 for the dehydration of glycerol to acrolein via semi-batch reaction technique.
- As a catalyst in the form of sulfonated heteropoly acid salts for the synthesis of isoamyl isovalerate.
- In the preparation of molybdenum imido alkylidene NHC catalysts, which are used in biphasic olefin metathesis.
- To prepare water-stable SO3H-functionalized Br?nsted acidic task-specific ionic liquids (TSILs).
Использование
3-(1-Pyridinio)-1-propanesulfonate is a non detergent sulfobetaine used as a mild solubilizing and stabilizing agent for halophilic malate dehydrogenase, halophilic elongation factor Tu (hTu), pig heart malate dehydrogenase, chicken egg w hite lysozyme and E. coli beta-galactosidase. Preserves the antigenic conformation of serine protease gp76. Does not interfere with colorimetric assays using p-nitrophenylphosphate and o-nitrophenyl -b-D-galactopyranoside as substrates. Reduces aggregation and significantly improves protein renaturation. Zwitterionic over a wide pH range. Does not absorb significantly in the near-UV range. Ca n be easily removed by dialysis.прикладной
