Background:

Diclofenac-d₄contains four deuterium atoms on the benzene ring. It is intended for use as an internal standard for the quantification of diclofenac by GC- or LC-mass spectrometry. Diclofenac is a non-selective COX inhibitor.^1,2,3It inhibits human COX-1 and -2 with IC₅₀values of 0.9-2.7 and 1.5-20 µM, respectively.^1,2Diclofenac inhibits ovine COX-1 and -2 with IC₅₀values of 60 and 220 nM, respectively.³
