title: Identification of organic N-chloramines in vitro in stomach fluid from the rat after chlorination.
abstract: Amino acids were identified and quantified in the stomach fluid recovered from animals fasted 8, 24, and 48 h. After in vitro chlorination of stomach fluid, three chloramino acids, N-chloroglycine, either N-chloroleucine or N-chloroisoleucine, and N-chlorophenylalanine, were identified by GC/MS analysis of dansylated methyl ester derivatives. Formation of N-chlorovaline and N-chloroserine was suggested by their HPLC retention times, but their identification could not be confirmed by GC/MS data.
