On the basis of the results of both the
studies and applying the weight of evidence approach, it can be
concluded that the test chemical is not hydrolysable.
Two studies have been reviewed to
determine the hydrolysis reaction of the test chemical. The studies are
as mentioned below:
In first study it was mentioned that
the compounds containing carbon, hydrogen, and oxygen, esters and
epoxides are susceptible to hydrolysis under the OECD test conditions
(OECD Guideline 111). For these hydrolysis reactions to occur, there
must be 1) an electrophylic carbon atom which is 'attacked' by oxygen;
and 2) a 'leaving group' which departs from the attacked carbon atom.
The hydrolysis reaction of test chemical would occur by attack of water
or OH- at C1, because this is the most electropositive carbon in this
molecule due to the electron withdrawing effect of the phenolic OH group
and the product of this reaction would be test chemical itself,
indicating that there would be no net hydrolysis.
Therefore, test chemical would be
hydrolytically stable under the conditions of the OECD test (OECD
Another study was reviewed fom
authoritative database (HSDB) in this the test chemical is not expected
to undergo hydrolysis in the environment due to the lack of hydrolyzable
functional groups which menas it is stable and not hydrolysable.
On the basis of the results of both
the studies mentioned above and applying the weight of evidence
approach, it can be concluded that the test chemical is not hydrolysable.
