4-бромбензойной кислота

Химические свойства

White to light yellow crystal powder

Использование

4-Bromobenzoic acid was used to study the metabolic fate of 2-,3-and 4-bromo benzoic acids in rat hepatocytes incubation using high temperature liquid chromatography. It was used in bromine-specific detection of the metabolites of 2-,3-and 4-bromobenzoic acid in the urine and bile of rats by inductively coupled plasma mass spectrometry. It is also used as an intermediate for the synthesis of agrochemicals, pharmaceutical, chemical intermediates and liquid crystals.

Определение

Colorless to red crystals.

Угроза здоровью

ACUTE/CHRONIC HAZARDS: Explodes above its melting point.

Методы очистки

Crystallise the acid from MeOH, or MeOH/water mixture, 90% EtOH and Et2O. The methyl ester has m 81o from Et2O or dilute MeOH. The anilide has m 197o (from EtOH).
