Practical, stable standards for the reversed phase HPLC analysis of peptidic leukotrienes

Abstract The stable glutathione derivatives 1 , R = n -C 6 H 13 and R = n -C 8 H 17 , are useful as reference compounds for the identification and quantitation of leukotrienes C 4 , D 4 and E 4 by reversed phase HPLC analysis.
