✦ Synopsis

A technique is described for maintaining thiol solutions in their reduced form by the addition of tributylphosphine which can subsequently be removed by extracting with sulfur in chloroform.

Aqueous solutions of thiols are rapidly oxidized by air during storage, and hence standard solutions of reagents such as cysteine and glutathione can be kept for only very short periods. This autoxidation is catalysed by traces of iron and copper salts (for a review, see Ref. 1), and hence 137
