1HPLC chromatogram

Data file: PL-2610-026-HPLC.raw · Column C18, 150 × 4.6 mm · UV 214 nm

Peak plot drawn from the integrated peak table (area %, log scale); it is not the instrument trace, which is retained in PL-2610-026-HPLC.raw. † Nominal reference retention time for the assigned impurity; the main-peak RT is observed in this lot. Area % is per component (each component main peak + its impurities = 100%).
