Description of key information

The results of pH 4.0, pH 7.0 and pH 9.0 showed no significant degradation of ucb 6474 at 50°C. The degradation of ucb 6474 was less than 10 % after 5 days. According to the EEC Directive 92/69, Section C.7, it can be concluded, that the estimated half-life time is higher than one year under representative environmental conditions (25°C), Therefore, ucb 6474 was considered to be hydrolytically stable, and no furter testing was necessary.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 yr
at the temperature of:
20 °C
