N-methacryloyloxy-5-aminosalicylic acid (MASA) has recently been used as an adhesive primer in restorative resin systems. To monitor the biological activity of MASA, we studied changes in NMR-chemical shifts (delta H) and the differential scanning calorimetry (DSC) phase transition temperature (Tm)
