General description

Dimethyl itaconate undergoes enantioselective Rh(I)-catalyzed hydrogenation which can be enhanced by appropriate choice of substituents on aromatic ring of (1,2-diarylphosphinoxy)cyclohexane.

Application

Dimethyl itaconate may be used in functionalization of isotactic poly(propylene). It was used in crosslinking of polyesters: poly(isosorbide itaconate)and poly(isosorbide itaconate-co-succinate).

Questions

  1. If my product is in the liquid format, what is its concentration? How should I calculate its concentration?

    1 answer
    1. The concentration of this product can be determined using the lot-specific purity reported in the Certificate of Analysis, the density, and the compound molecular weight. This product has a density of 1.124 g/mL and a molecular weight of 158.15 g/mol. The minimum purity is 96.5%, thus the molarity will vary slightly from lot to lot. The molarity can range from 6.86M (96.5%) to 7.11M (100%).
