Materials and methods

Test guideline
Qualifier:
according to
Guideline:
other:
Principles of method if other than guideline:
Redox titrations are based on a reduction-oxidation reaction between an oxidizing agent and a reducing agent. A potentiometer or a redox indicator is usually used to determine the endpoint of the titration. In permanganometry a slight faint persisting pink color signals the endpoint of the titration because of the color of the excess oxidizing agent potassium permanganate
GLP compliance:
no

Applicant's summary and conclusion

Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
3-amino-4-methoxybenzenesulphonic acid was found to be oxidizing since 261.15 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of 3-amino-4-methoxybenzenesulphonic acid.
Executive summary:

3-amino-4-methoxybenzenesulphonic acid was found to be oxidizing since 261.15ml of KMnO4 was required for getting the end point of the redox titration for 100 g of 3-amino-4-methoxybenzenesulphonic acid. But this does not completely support the oxidising property of the substance and so cannot be concluded that the substane will have oxidising property.
