Contamination of dipeptide by polymer stabilizers leached from gloves and packaging during scale-up

In dipeptide production, it was observed that a water solution of a peptide became turbid. The origin of turbidity was monitored and identified by LC-MS analysis. The impurities, derived from natural rubber gloves, and polyethylene bags caused the turbidity when the wet cake of the peptide contacted them.

FACTORS DETERMINING THE REACTIVITY OF PHOSPHOROUS TRIESTERS IN REACTIONS WITH CUMENE HYDROPEROXIDE

The kinetics of reduction of cumene hydroperoxide with a wide range of aliphatic and aromatic phosphorous triesters in benzene were studied by the polarographic method.Factors determining the reactivity of the phosphites in this reaction were investigated by the method of correlation analysis.
