Description of key information

The half life of p-TSH at 20 °C was:

138.63 h at pH 4

38.51 h at pH 7

40.77 h at pH 9

These data suggest that p-TSH will degrade hydrolytically at environmentally relevant pH and temperature conditions. The primary degradation products are hydrazine and p-Toluenesulfonic acid.
