Highly sensitive fluorescent labeling reagents, 2-(alkyloxy)-4-(2-phthalimidinyl)phenylsulfonyl chlorides (alkyloxy = methoxy, ethoxy, and propoxy; MPS-Cl, EPS-Cl, and PPS-Cl, respectively), for determination of phenols by high-performance liquid chromatography (HPLC) have been developed. These reagents react with phenols in basic medium to produce
