NDSB-201

Non-detergent sulfobetaines are zwitterionic substances, which do not form micelles due to too short hydrophobic side chains even at high concentrations. NDSB-201 is used for solubilization of proteins for proteomic applications.

It prevents protein aggregation and non-specific interactions of proteins and  facilitates the renaturation of chemically and thermally denatured proteins.
NDSB-201 has also successfully been used as catalyst for the chlormethylation of alkylbebzenes

Synonym: Non-Detergent Sufobetaine 201; PPS; 3-(1-Pyridino)-1-propane sulfonate; 1-(3-Sulfo-propyl)pyridinium betaine

CAS registry number: [15471-17-7]

Molecular formula: C8H11NO3S

Relative molecular mass (Mr): 201.2
