The authors stated the following in their materials section:

"Flonicamid (CAS Registry No. 158062-67-0, 99.7%, purity, Lot No. 272785), 4-trifluoromethylnicotinic acid (TFNA, CAS
Registry No. 158063-66-2, 99.4% purity, Lot No. 404593), 4-trifluoromethylnicotinamide (TFNA-AM, CAS Registry No. 158062-71-6,
100% purity, Lot No. 275591), and N-(4-trifluoromethylnicotinoyl)glycine (TFNG, CAS Registry No. 207502-65-6, 99.4% purity, Lot No
