One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 623-33-6, Name is H-Gly-OEt.HCl, formurla is C4H10ClNO2.

Tissue Distribution, Accumulation, and Metabolism of Chiral Flufiprole in Loach (Misgurnus anguillicaudatus)
Flufiprole is an insecticide used in the rice field and may pose a potential threat to aquatic organisms including loach. To investigate the transformation products of flufiprole in loach, the accumulation, elimination, and tissue distribution in vivo as well as the metabolism in vitro at the enantiomeric level were studied. Flufiprole enantiomers rapidly accumulated and were metabolized to flufiprole sulfone, fipronil, and flufiprole amide in the tissues. Enantiomeric fractions showed the preferential accumulation and degradation of S-flufiprole. The residue of the chiral metabolite flufiprole amide was also enantioselective. The individual enantiomer treatment indicated that S-flufiprole was preferentially metabolized to flufiprole sulfone and R-flufiprole to fipronil. The metabolites were more persistent than flufiprole with longer half-lives. The metabolism in liver microsomes also reached consistent conclusions. The dietary risk assessment indicated that flufiprole would not cause unacceptable threats to human health. However, the metabolites of flufiprole should be considered in the risk evaluation.
