Additional information

The substance is a salt which is a reaction product of acid and base that retain their ionic character.

In addition, the dissociation constant on the single compound has been calculated, respectively.

The representative fatty acid part (in form of Dodecanoic acid, 2-sulfo and Tetradecanoic acid, 2-sulfo) were calculated with SPARC.

1) Dodecanoic acid, 2-sulfo:


calculated pKa= 4.21 at 25°C

2) Tetradecanoic acid, 2-sulfo:


calculated pKa= 5.49 at 25°C
