(+)-alpha-phenylglycine are significant contaminants at pharmaceutical intermediates production. To study processes for the destruction of contaminant L(+)-alpha-phenylglycine in acid aqueous solution we have investigated the transient species using both laser flash photolysis. The OH· reaction with L(+)-alpha-phenylglycine process was investigated and formed polymer. Furthermore, the results of steady-state analysis suggested that L(+)-alpha-phenylglycine removal was found to be more efficient with increasing applied dose. L(+)-alpha-phenylglycine, decreased by 44.50%, using a dose of 14kGy.
