A method for detecting traces of β-propiolactone, which was previously described by SCHMITZ-MASSE, has been modified and adapted to the analysis of protein solutions. Using this method, the rate of hydrolysis of β-propiolactone (β-Pl) was examined and β-Pl sterilized commercial products were analyzed for possible residual nonhydrolyzed β-Pl.

Abstract. A method for detecting traces of β‐propiolactone, which was previously described by Schmitz‐Masse, has been modified and adapted to the analysis of protein solutions. Using this method, the rate of hydrolysis of β‐propiolactone (β‐P1) was examined and β‐P1 sterilized commercial products were analyzed for possible residual nonhydrolyzed β‐P1.
