Additional information

Hydrolysis as a function of pH was performed under GLP compliance and used as the key study. The result showed FAT 45176/A at pH 4 has a half-life period of 12233.9 hours (about 1.4 years) at 25 °C, at pH 7 has a half-life period of 84.8 hours (about 3.5 days) at 25 °C, and is unstable at pH 9 with a half-life period of shorter than one day at 25 °C.
