The standards of 5-FU and uracil were purchased from Wako Pure Chemical Ind. Ltd. (Osaka, Japan), and the standard of tegafur was purchased from Tokyo Chemical Industry Co. Ltd. (Tokyo, Japan). The stable isotope-labeled internal standards (IS) for 5-FU and tegafur; 5-FU-13C,15N2 and tegafur-13C,15N2, respectively, were synthesized by Toronto Research Chemicals (Toronto, Canada) and that for uracil; uracil-15N2, was synthesized by Cambridge Isotope Laboratories Inc. (Andover, MA, USA). Ammonium formate used for preparing working solution was purchased from Wako Pure Chemical Ind. Ltd. (Osaka, Japan). All solvents (water, methanol, acetonitrile, ethyl acetate, and isopropyl alcohol) used in chromatography, mass spectrometry, liquid extraction, and sample preparation were of the highest analytical quality (HPLC or LC/MS grade).

Tegafur was purchased from Tokyo Chemical Industry UK Ltd. (Oxford, UK). 2,6bis(acrylamido)pyridine (BAAPy) [21] and 9-isobutyladenine [22] were synthesised as described previously. All other tested analytes, shown in Figure 1, ethyleneglycol dimethacrylate (EDMA), HPLC grade solvents and deuterated solvents were purchased from Sigma Aldrich (Gillingham, UK). 2,2'-Azobis(2,4-dimethylvaleronitrile) (ABDV) was purchased from Wako Chemicals GmbH and was used as received. Polymerisation inhibitors were removed from EDMA by filtration through a basic alumina column. 1 H NMR spectra were collected on a Bruker ECX 400 MHz NMR spectrometer. An Agilent 1100 HPLC instrument equipped with photodiode array detector and a Phenomenex Kinetex TM C18 column (5μm, 150 mm × 4.6 mm i.d.) was used for all chromatographic separations.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
