Applicant's summary and conclusion

Conclusions:
Because the target analyte was undetected in each centrifugated solution, so it can be confirmed that the water solubility of 10-oxo-10H-dibenzo[b,e]thiopyran-4-carboxylic acid is less than LODe of the HPLC method. LODe has been determined as 65.6 μg/L and pH value of each centrifugated solution is 6.0, so Water Solubility is “<65.6 μg/L (20℃, pH6.0)”.
