Molecular level differentiation between end-capped and intramolecular azofunctional oligo(ε-caprolactone) positional isomers through liquid chromatography multistage mass spectrometry

End‐capped and intramolecular azofunctional oligocaprolactones were characterized at molecular level by liquid chromatography electrospray ionization mass spectrometry (ESI MS) and NMR spectroscopy. The Disperse Red 19 (DR19) azofunctional oligomers, DC, were synthesized by ring‐opening oligomerizat...
