CAS:872005-48-6 | 1,6,7,12 - Tetra -t -butylphenoxy - N - N' - Dioctyl-perylene - 3,4,9,10 - Tetracarboxylic Dianhydride

Introduction of CAS:872005-48-6 | 1,6,7,12 - tetra -t -butylphenoxy - N - N' - dioctyl-perylene - 3,4,9,10 - tetracarboxylic dianhydride

Design of the Synthesis Pathway
The synthesis pathway for N,N-Dioctyl-1,6,7,12-Tetra-tert-butylphenoxyperylene-3,4,9,10-tetracarboxylic dianhydride involves the reaction of 1,6,7,12-tetra-tert-butylphenoxyperylene-3,4,9,10-tetracarboxylic acid with octanol and acetic anhydride to form the corresponding ester. The ester is then converted to the dianhydride by reaction with phosgene.
