Reference
Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
Data is from experimental study report
Qualifier:
according to guideline
Guideline:
other: as mentioned below
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

Description of key information

According to redox titration considerations, 2-tert-butylhydroquinone end point of the redox titration was obtained at 312.6 ml KmnO4/100g of analyte 2 -tert-butylhydroquinone..2-tert-butylhydroquinone was not found to exhibit oxidising property.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

2-tert-butylhydroquinone was found to exhibit mild oxidising property since 312.6 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of 2-tert-butylhydroquinone. Thus, the chemical is considered as non-oxidising for the purpose of classification.

Justification for classification or non-classification

2-tert-butylhydroquinone was found to exhibit mild oxidising property. Thus, the chemical shall be considered to be non-oxidising .
