Participants

Reaction Steps

A solution of 2,2′-dithiobis ethane sulfonic acid (2.5 g, containing 9% water, 8.1 mmol) in water (1.0 mL) was titrated with ammonium hydroxide aqueous solution (28-30% concentration, Aldrich) until the pH of the reaction solution was adjusted to 7.0. Overall 2.6 mL of ammonium hydroxide was used. Acetone (200 mL) was added to the reaction solution to precipitate the product. The resulting white solid was isolated by filtration and dried under high vacuum to give 2.10 g of product (82% yield). The purity of the product was 98.2% from HPLC analysis.
