Tetrabutylammonium bromide, with the cas register number 1643-19-2, is also called TBAB. Tetrabutylammonium bromide(TBAB) is a quaternary ammonium salt with a bromide counterion commonly used as a phase transfer catalyst. Tetrabutylammonium bromide is an ion-pair reagent for the synthesis of Bacampicillin and sultamicillin. It could stable under normal temperatures and pressures. Hygroscopic: absorbs moisture or water from the air. It should avoid the condition like incompatible materials, dust generation, excess heat, exposure to moist air or water. It is not compatible with strong oxidizing agents. And also prevent it to broken down into hazardous decomposition products: nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen bromide. However, its hazardous polymerization will not occur.

Physical properties about Tetrabutylammonium bromide are: (1)ACD/LogP: -1.715; (2)ACD/LogD (pH 5.5): -1.72; (3)ACD/LogD (pH 7.4): -1.72; (4)ACD/BCF (pH 5.5): 1.00; (5)ACD/BCF (pH 7.4): 1.00; (6)ACD/KOC (pH 5.5): 2.78; (7)ACD/KOC (pH 7.4): 2.78; (8)#H bond acceptors: 1; (9)#Freely Rotating Bonds: 12
