DescriptionEfflorescent yellow-orange needles of PQQ are formed on recrystallising from H2O by addition of Me2CO, or better from a supersaturated aqueous solution, as it forms an acetone adduct. [Forrest et al. Nature 280 843 1979.] It has also been purified by passage through a C-18 reverse phase silica cartridge or a silanized silica gel column in aqueous solution whereby methoxantin remains behind as a red-orange band at the origin. This band is collected and washed thoroughly with dilute aqueous HCl (pH 2) and is then eluted with MeOH/H2O (7:3) and evaporated in vacuo to give the coenzyme as a red solid. It has also been purified by dissolving it in aqueous 0.5M K2CO3 and acidified to pH 2.5 whereby PQQ precipitates as a deep red solid which is collected and dried in vacuo. Methoxantin elutes at 3.55 retention volumes from a C18 _Bondapak column using H2O/MeOH (95:5) + 0.1% AcOH pH 4.5. It has UV max at 247 and 330nm (shoulder at 270nm) in H2O and max at 250 and 340nm in H2O at pH 2.5. With excitation at ex 365nm it has a max emission at 483nm. The 13C NMR has : 113.86, 122.76, 125.97, 127.71, 130.68, 137.60, 144.63, 146.41, 147.62, 161.25, 165.48, 166.45, 173.30 and 180.00ppm. When a solution in 10% aqueous MeCO is adjusted to pH 9 with aqueous NH3 and kept at 25o for 30minutes, the acetone adduct is formed; UV has max at 250, 317 and 360nm (H2O, pH 5.5), and with ex at 360nm it has max fluorescence at max at 465nm; and the 13C NMR [(CD3)2SO, TMS] has : 29.77, 51.06, 74.82, 111.96, 120.75, 121.13, 125.59, 126.88, 135.21, 139.19, 144.92, 161.01, 161.47, 165.17, 168.61, 190.16 and 207.03ppm. It also forms a methanol adduct. When it is reacted with Me2SO4/K2CO3 in dry Me2NCHO at 80o for 4hours, it forms the trimethyl ester which has m 265-267o(dec) [260-263o(dec) also reported] after recrystallisation from hot MeCN (orange crystals) with UV max at 252 and 344nm (H2O) and 251, 321 and 373nm (in MeOH; MeOH adduct ).
