hexane-1-sulfonic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Glycerine, ethyl alcohol and methylene chloride were purchased from Frutarom; enzymatically hydrolyzed gelatin with average molecular weight of 10,000-12,000 was purchased from Croda; hexanesulfonic acid was purchased from BDH; methylmethacrylate-methacrylic acid copolymers were provided from Rhom Pharma; 1-PLA with Mw of 427,000 and Mn of 224,500 was purchased from Boehringer Ingelheim; triethyl citrate was provided by Morflex; ethylcellulose was provided by Teva; polyvinyl pyrrolidone was provided by Taro; glutaraldehyde 25% and acetonitrile were purchased from Merck; chloroform, orthophosphoric acid and trichloroacetic acid were purchased from Baker. All solvents were of analytical grade, except acetonitrile which was HPLC grade.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Following a procedure analogous to that of Example 1, hexane-1-sulphonic acid and desferrioxamine-B are reacted to give the hexane-1-sulphonate salt of desferrioxamine-B. Mp 138° C.
