ZWITTERGENT® 3-14 Detergent, Calbiochem®, MilliporeSigma

This synthetic zwitterionic detergent retains its zwitterionic character over a wide pH range.

Synonyms: n-Tetradecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate
Form: White solid
Storage: +15°C to +30°C
Toxicity: Irritant
CMC: 100 - 400 μM
Aggregation Number: 83

The zwitterionic character is attributed to the presence of both a strongly basic quaternary ammonium ion and an acidic sulfonate ion of equal strength. This ionic balance presumably prevents irreversible binding of the detergent to either anionic or cationic compounds.

: Following reconstitution, refrigerate (4°C). Aqueous stock solutions are stable for several months at 4°C.
