A fluorinated cinnamic acid building block

Used as a synthesis precursor for APIs


Specifications | MSDS | Literature and Reviews


trans-3,4-Difluorocinnamic acid (CAS number 112897-97-9) is a difluoro-substituted benzene featuring a trans-propenoic acid. trans-3,4-Difluorocinnamic acid is readily used for the synthesis of substituted isoquinolones through Curtius rearrangement. Substituted isoquinolones are found to be effective 5-HT3 antagonists (infective dose ID50 of 0.35 μg/kg) in anticancer treatments.

trans-3,4-Difluorocinnamic acid is also utilized in the synthesis of psammaplin A derivatives as radiosensitizers for human lung cancer. The product derived from trans-3,4-difluorocinnamic acid demonstrates a potency of 16.14 μM.
