No. The $250 test covers identity, purity and quantity by HPLC-UV for purity and quantity and LC-MS for identity. Full testing to the USP Primaquine Phosphate monograph is available and quoted.
Quinocide is a positional isomer of primaquine that can form during synthesis. It has the same mass as primaquine, so it is controlled by HPLC separation rather than by mass alone.
Primaquine is supplied as the diphosphate salt, so the salt weighs much more than the base. Results are converted between primaquine phosphate and primaquine base using the molecular weights.
Primaquine phosphate darkens with light and air, so samples should be kept closed and protected from light before testing.
