Derivatization of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) with butyl alcohols

As a continuation of our earlier research, the paper reports progress in th e study on improvement of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furan one (MX) determination in water. In particular, the effect achieved as resu lts of modification of MX with butyl alcohols (n-butanol, isobutanol, sec-b utanol and tert-butanol) is reported. Sec-butanol derivatization permits se paration of MX enantiomers in the form of diastereoisomers, Isobutanol deri vatization leads to formation of sextet of fragmentation ions of high abund ance, which can improve identification of MX in environmental samples.
