Chromatogram and related spectra of synthesized 2 (BRS; high resolution mass spectrometry mode). The red chromatogram represents UV absorbance at 440 nm and serves as a point of reference for identified ions. The superimposed chromatogram represents extracted ion chromatograms for 663.2130 and 581.2406 m/z ± 0.5. It should be noted that the 581.2451 m/z ion only appears at 9.7 minutes. The 663.2150 and 663.2158 m/z ions were observed to be the major abundant ion under peaks (2) and (3) at 440 nm and 412 nm respectively.
