EC number: 816-324-8
CAS number: 2044770-20-7
Hydrolysis as a function of pH was determined according to OECD
Guideline No. 111 and Council Regulation (EC) No. 440/2008, Method C.7
for the test itemPU-2017-766(batch number: UR18201873) from 2019-05-23
to 2019-05-28 at Noack Laboratorien, 31157 Sarstedt, Germany.
Analyses of the test item PU-2017-766were performed via LC‑MS/MS
on a reversed phase analytical column using the test item as external
standard. The analytical method was validated with satisfactory results
with regard to linearity, accuracy, precision and specificity.
The study was conducted with test item concentration of 100 mg/L
in buffer solutions at pH 4, 7 and 9 at a test temperature of 50 °C
(preliminary test). Samples were taken at test start (0 hours) and test
end (120 hours). Pure test systems (buffer solution pH 4, 7 and 9) were
analysed at test start and test end and there was no analytical
interference with the test item.
No significant elimination was observed and therefore the test
item was considered as hydrolytically stable under this condition and a
half-life of > 1 year could be assumed for environmental typical
The test item PU-2017-766 was found to be hydrolytically stable at all
