Karl Fischer reagents have been used for water determination in analytical laboratories for more than half a century. The original formulation, being based on pyridine became out of favour during the past 30 years due to the accompanying hazard and unpleasant odour. Pyridine-free reagents have therefore increased in popularity and now account for the majority of KF titrations.
