Potassium bromide (KBr) yog ntsev, dav siv los ua cov tshuaj tiv thaiv kab mob thiab tshuaj sedative nyob rau xyoo 19th thiab thaum ntxov 20th centuries, nrog kev siv ntau dhau ntawm lub khw muag khoom txuas mus rau xyoo 1975 hauv Asmeskas. Nws qhov kev txiav txim yog vim yog bromide ion (sodium bromide zoo sib npaug). Potassium bromide yog siv los ua cov tshuaj kho tsiaj, ua tshuaj tiv thaiv kab mob rau dev.

Raws li cov txheej txheem, potassium bromide yog cov hmoov dawb crystalline hmoov. Nws yog dawb soluble nyob rau hauv dej; Nws tsis yog soluble hauv acetonitrile. Nyob rau hauv ib tug dilute aqueous tov, poov tshuaj bromide saj qab zib, nyob rau hauv ntau dua concentrations nws saj iab, thiab qab qab ntsev thaum lub concentration yog ntau dua [los ntawm ntau npaum li cas?] Cov teebmeem no feem ntau yog vim cov khoom ntawm cov poov tshuaj ion-sodium bromide saj. ntsev ntawm txhua qhov concentration. Nyob rau hauv siab concentration, poov tshuaj bromide muaj zog irritates lub plab mucous daim nyias nyias, ua rau xeev siab thiab ntuav (ib tug raug cov nyhuv ntawm tag nrho cov soluble poov tshuaj ntsev).
