In a citrate-borate-phosphate buffer, 5 mM tinidazole solutions exhibi
ted maximum stability around pH 4.0-5.0. The hydrolysis of tinidazole
was mostly a first-order reaction. At pH 10.0 and 60-80 degrees C, tin
idazole had an activation energy of 122 kJ mol(-1) for hydrolysis. It
was postulated that tinidazole decomposes by different mechanisms unde
r basic and neutral/acidic conditions.
