Any other information on results incl. tables

 The detector calibration was found to be linear over the range 0 to 30 mg/l of standard solutions in water with a regression coefficient of 0.9998. The data shows that ATBS was unstable in both methanol and ethanol following the accelerated storage procedure, with greater than 5% degradation evident after the test period.

Applicant's summary and conclusion

Conclusions:
ATBS was found to be unstable in both methanol and ethanol.
