A sensitive, accurate and precise bioanalytical method was developed for the determination of Cidofovir diphosphate in monkey and rabbit tissues using LCMS/ MS. The method was developed to evaluate concentration levels of the active metabolite in various monkey and rabbit organs and tissues in support of a maximum tolerated dose study .

The Precellys®24 allowed validation of this method over a linear range of 5 to 1000 pg/mg. Full validations were performed for monkey and rabbit liver tissue. Validation experiments included intra- and inter-day precision and accuracy, selectivity/specificity, recovery, matrix effect, lower and upper limit of quantification and stability tests. The accuracy for monkey liver ranged from 97.7% to 101% and the precision ranged from 4.3% to 8.2% (CV). For rabbit liver, the accuracy range was 101% to 102% and the precision range was 4% to 7.5% (CV).
