Diclofenac-d4 contains 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.1,2,3 It inhibits human COX-1 and -2 with IC50 values of 0.9-2.7 and 1.5-20 µM, respectively.1,2 Diclofenac inhibits ovine COX-1 and -2 with IC50 values of 60 and 220 nM, respectively.3

Diclofenac Concentrations in Post-Mortem Specimens-Distribution, Case Reports, and Validated Method (UHPLC-QqQ-MS/MS) for Its Determination
Toxics 2022 Jul 26;10(8):421.PMID:35893854DOI:10.3390/toxics10080421.
The aim of the research was to establish a sensitive method for the quantification of diclofenac in postmortem samples. The developed method was applied in six cases: three fetuses in which the use of abortion pills by their mothers was suspected, one case of duodenal ulcer perforation, one case of traffic accident with fatal outcome, and one acute renal failure in which the distribution of diclofenac was examined. The analyses were performed using liquid-liquid extraction of postmortem samples and the quantification of diclofenac via ultra-high performance liquid chromatography, coupled with triple quadrupole tandem mass spectrometry. Gradient elution using a C18 column was applied. Electrospray ionization measurement in positive multiple reaction monitoring mode was used. Diclofenac-d4 was used as an internal standard. The validation parameters were as follows: lower limit of quantification: 0.5 ng/mL, linearity of calibration curve: 0.5-500 ng/mL, intra- and interday accuracies and precisions: not greater than 15%; recovery values: 72.0-102.2%, and matrix effect: 2.2-28.0%. The developed method enabled the determination of diclofenac in human postmortem biological fluids (blood, urine, vitreous humor, bile, and stomach content), tissues (placenta, kidney, liver, and heart), and in exhumated fetus bones, with high recovery, sensitivity, precision, and accuracy.
A multiresidue liquid chromatographic/tandem mass spectrometric method for the detection and quantitation of 15 nonsteroidal anti-inflammatory drugs (NSAIDs) in bovine meat and milk
Anal Bioanal Chem 2015 Jun;407(15):4485-94.PMID:25814273DOI:10.1007/s00216-015-8634-1.
This study concerns a validated liquid chromatographic/tandem mass spectrometric (LC-MS/MS) multiresidue method for the simultaneous detection, identification, and quantitation of 15 nonsteroidal anti-inflammatory drugs (NSAIDs) in bovine meat and milk. The NSAIDs considered are carprofen, diclofenac, flufenamic acid, flunixin (5-hydroxyflunixin as marker metabolite in milk), ketoprofen, mefenamic acid, meloxicam, 4-methylaminoantipyrine (marker metabolite of metamizole in meat and milk), naproxen, niflumic acid, phenylbutazone (and metabolite oxyphenbutazone), ramifenazone, salicylic acid, and tolfenamic acid. These compounds were chosen as representatives of different chemical subclasses of NSAIDs. Flunixin-d3, Diclofenac-d4, 4-aminoantipyrine-d3, and phenylbutazone-d10 were used as internal standards. Performance characteristics were validated according to the Commission Decision 2002/657/EC (Off J Eur Communities, L221: 8-36). Recovery percentages varied between 81 and 114% for bovine meat and between 79 and 118% for milk. Repeatability percentages were within the range of 1-12% for meat and between 1 and 17% for milk, whereas the intralaboratory reproducibility varied between 3 and 19% for meat and between 3 and 23% for milk. The decision limit and the detection capability for bovine meat were within the range of 0.5-579 μg kg(-1)and 0.6-642 μg kg(-1), respectively. Those for milk were within the range of 0.12-55 μg kg(-1) and 0.14-61 μg kg(-1), respectively. The methods developed were successfully applied for proficiency test samples and routine samples analyzed in the laboratory. The methodology concerns fast, user-friendly, and sensitive methods, which can be easily extended for other compounds and matrices. In general, such multiresidue methods contribute to the reduction of human exposure to these veterinary drug residues by consumption of contaminated bovine-derived products such as meat and milk.
