HPLC of Formula: 707-61-9. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, is researched, Molecular C11H13OP, CAS is 707-61-9, about MALDI-TOF/TOF CID Study of Polycarbodiimide Branching Reactions. Author is Gies, Anthony P.; Heath, William H.; Keaton, Richard J.; Jimenez, Jorge J.; Zupancic, Joseph J..
A combination of MALDI-TOF MS and TOF/TOF collision-induced dissociation (CID) experiments was conducted on toluene diisocyanate (TDI) based carbodiimide and Ph isocyanate (PI) carbodiimide mixtures to examine their degradation mechanisms and identify “”fingerprint”” side products associated with each of their synthesis. Findings include the first observance of the 3-methyl-1-phenyl-2-phospholene-1-oxide (MPPO)/carbodiimide (CDI) catalyst-attached intermediate and the use of CID fragmentation to verify its chem. structure and degradation processes. This work is significant for two reasons: (1) it identifies extensive branching as the root-cause of viscosity build-up in carbodiimides and (2) it presents a BF3-initiated mechanism leading to polyguanidine formation.
