Applicant's summary and conclusion

Conclusions:
3-amino-4-methoxybenzenesulphonic acid was found to be stable in organic solvent dichloro methane and no degradation products were formed after 24 hours as evident from the comparative GC-MS chromatogram obtained at 0 hours and that obtained after 24 hours.
