Description of key information

In accordance with column 2 of Annex VII of the REACH regulation, the study does not need to be conducted since there are no chemical groups associated with explosive properties present in the molecule of  5-oxo-1-(4-sulphophenyl)-2-pyrazoline-3-carboxylic acid (Common Name: Pyrazolone T). Thus, the chemical is likely to be "Non explosive". Hence this end point was considered for waiver
