A test kit for the quantitative determination of narcotic drugs comprising (A) series of sealed vessels, each vessel containing a deuterium free isotopologue of a narcotic drug in exactly defined concentrations and quantities, wherein the isotopologue differs from vessel to vessel and—wherein the quantities of the isotopologue differ from vessel to vessel or are the same for all vessels; and/or (B) series of sealed vessels, each vessel containing in exactly defined concentrations and quantities the same isotopologue in quantities which differ from vessel to vessel; wherein the free isotopologues are selected from narcotic drugs; prodrugs, salts, solvates, hydrates and polymorphs and contain at least three stable isotopes selected from the group consisting of

in a human absorption, distribution, metabolism, and excretion study and a stable isotope labeled analog for use as a standard in bioanalytical assays to accurately quantify the concentration of the drug in biological samples. Carbon-14 labeled Avagacestat was synthesized in seven steps in a 33% overall yield from carbon-14 labeled potassium cyanide. A total of 5.95 mCi was prepared with a specific
