Additional information

The dissociation of the substance tetraesters from esterification of pentaerythritol with pentanoic, heptanoic and isononanoic acids (former CAS 68424 -30 -6) was determined by QSAR calculations with SPARC (v4.5) for the two exemplary components covering both ends of the substance specification. No dissociation could be determined within the range pH = -0.2 -14.
