Quercetin D5 is a deuterated internal standard for the natural compound quercetin, its chemical structure is essentially the same as quercetin, except that five deuterium (D) atoms replace five hydrogen (H) atoms in the A ring[1]. By monitoring the specific mass spectral ion pairs of Quercetin D5 and natural quercetin and calculating their response ratios, a highly precise and accurate standard curve can be constructed, enabling the absolute quantification of extremely low concentrations (nanogram/mL level) of quercetin in biological samples[2, 3]. Using Quercetin D5 as an internal standard allows for the accurate determination of quercetin concentrations in the plasma and tissues of rats after oral administration, and the calculation of reliable pharmacokinetic parameters[4]. Quercetin is a natural flavonoid compound with applications in various research areas, including anti-inflammatory, anti-allergic, antiviral, cardiovascular protective, and anti-cancer activities[5].
