EC number: 947-794-3
CAS number: -
The tests were performed according to OECD Guidelines for Testing of
Chemicals, Section 1 – Physical-Chemical Properties, OECD 111
(Preliminary test, Tier 1), Council Regulation (EC) No 440/2008,
Guideline Part C – Methods for the Determination of Ecotoxicity, C.7.
“Abiotic Degradation: Hydrolysis as a Function of pH”.
The hydrolysis behaviour of HPP 12879 -1 was investigated at 50 °C and
pH 4, pH 7 and pH 9 over a period of 5 days according to OECD 111
(Preliminary test, Tier 1). The stability was monitored by HPLC analysis
According to the data of the sponsor and investigated and reported in
the material balance (CURRENTA file no.: 2014/0048/03) the test item
consists of three different Mannich Bases (2x substituted, 3x
substituted and 4x substituted) as major constituents representing a
total content of > 99 %.
The developed analytical HPLC-UV method can distinguish between these
similar components. Therefore the hydrolytically behaviour of each
component could be investigated and monitored separately.
At all three pH-values hydrolysis < 10 % was detected for each of the
three components. Thus, HPP 12879 -1 can be considered as hydrolytically
stable at 25 °C, too.
