A nucleotide of nicotinic acid which is produced from quinolinic acid by quinolinate phosphoribosyltransferase via transfer of a phosphoribose group. It is an intermediate of nicotinic acid adenine dinucleotide (NaAD) which is then converted to NAD via amidation and in turn converted to NADPH.Solubility (Turbidity, 50mg/ml, H2O): Colorless, clearWater (by Karl Fischer): ≤11.5%EMM, anhydrous (lambda max 265-267nm, pH 7.0): 4.0-4.5
