A promising approach is the nucleophilic neutralization, scope of this review, which focuses on the molecular nucleophiles hydroxide, imidazole derivatives, alpha nucleophiles, amines and other nucleophiles. A reactivity mapping is given correlating the pathways and reaction efficiency with structural dependence of the nucleophile (basicity) and the organophosphate (electrophilic centers, P=O/P=S shift, leaving and non-leaving group). Reactions extremely unfavorable (>20 years) can be reduced to seconds with various nucleophiles, some which are catalytic. Although there is no universal nucleophile, a lack of selectivity in some cases accounts for plenty of versatility in other reactions. The ideal neutralization requires a solid mechanistic understanding, together with balancing factors such as milder conditions, fast process, selectivity and less toxic products. To evaluate compounded famciclovir suspensions for accuracy, precision, and consistency in drug content. Two compounded famciclovir concentrations were evaluated (250 and 400mg/mL, 30 preparations total from nine 503A compounding pharmacies) with U.S. Food and Drug Administration (FDA)-approved famciclovir tablets as control. Drug quantification via high-performance liquid chromatography (with famciclovir reference standard and pramipexole internal standard) was performed at 0, 14, and 28days with concentrations of 90%-110% of labeled dose considered acceptable (US Pharmacopoeia standards). FDA-approved tablets from three different manufacturers were found to be accurate and precise with acceptable drug content. A significantly greater mean deviation from labeled content was noted for 400mg/mL suspensions (-52.9%) compared to 250mg/mL suspensions (-18.0%). When assessing time points separately, 15/63 (24%) samples of 250mg/mL and 0/27 (0
