Self-matrix activity of organotin polyether ester polymers containing alpha-cyano-4-hydroxycinnamic acid

Polymers derived from reacting organotin dihalides and the matrix alpha-cyano-4-hydroxycinnamic acid act as their own matrix agent when performing MALDI MS. Ion fragments containing two and more repeat units are formed. MALDI MS results for the dioctyltin product are reported using other combinations of additives. Addition of sodium sulfate, not a matrix agent, also gives ion fragment clusters containing two repeat units. Use of addition of only...
