Identification of Halohydrins as Potential Disinfection By‐Products in Treated Drinking Water

In 2001, two potential disinfection by‐products (DBPs) were tentatively identified as 1‐aminoxy‐1‐chlorobutan‐2‐ol (DBP‐A) and its bromo analogue (DBP‐B) (Taguchi 2001). Subsequently it became clear, by consulting an updated version of the NIST database, that their mass spectra are close to those of the halohydrins 4‐chloro‐2‐methylbutan‐2‐ol and 3‐bromo‐2‐methylbutan‐2‐ol. To establish the structures of these DBPs, additional mass …
