Per literature povidone forms molecular adducts in solution with salicylic acid and tannin among others. My compounds of interests have similar functional groups in their stuctures and I cannot release API from the PVP-complex prior HPLC analysis.
Has any of you had similar issues and do you have any tips for developing efficient sample preparation?
Best regards,
