3-(1-Pyridinio)-1-propanesulfonate

Description

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.

Chemical properties

White to Off-White Solid.

The Uses of 3-(1-Pyridinio)-1-propanesulfonate

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.

Synthesis

In the equipped with a stirrer, thermometer, Calcium chloride drying tube and dropping funnelNecked flask was charged with 6.10g (0.05 mol)1,3-propanesultone and 150 mL of ethyl acetate was added and stirred until 1,3-propanesultone was dissolved. The flask was heated to 60°C in an oil bath equipped with methyl silicone oil. A solution of 5.14 g (0.065 mol) of pyridine was slowly added dropwise 50 mL of ethyl acetate, after the completion of the dropwise addition (dropwise time: 30 min)Insulation reaction 2h, pressure filtration, the residue was washed with ethyl acetate, vacuum drying, to give 3-(1-Pyridinio)-1-propanesulfonate 8.64 g. The yield was 86.0%.
