For the hydrolysis study, the nature of MK92K made the assessment of hydrolysis technically challenging. MK92K is considered to be a UVCB substance comprising multiple components, of similar chemical functionality, in varying proportions. A quantitative assessment of these components would therefore present considerable technical difficulty, as it would not be readily apparent for many of the components whether any change had taken place. It is considered therefore that in the absence of a suitably sensitive analytical technique, the hydrolysis rate could not be determined.
