Nine model analytes, one analog, six MEL haptens, six NIA haptens, two SBA-NOR conjugates, and one ABM hapten were fully synthesized in 2-10 steps. The detailed synthetic procedures are provided in the Supplementary Information. The chemical structures of all analytes were confirmed by nuclear magnetic resonance spectrometry DRX-300 from Bruker (Billerica, MA, USA) and high-resolution mass spectrometry from Agilent Technologies (Santa Clara, CA, USA).
