(6E,10E)-2-Bromo-2,6,10-trimethyl-12-[(tetrahydro-2H-pyran-2-yl)oxy]-6,10-dodecadien-3-ol is an intermediate in the synthesis of Farnesyl Pyrophosphate Triammonium Salt-13C3 (F102473). Farnesyl Pyrophosphate Triammonium Salt-13C3 is the labelled form of Farnesyl Pyrophosphate Triammonium Salt (F102470), which is an isoprenoid from the intracellular mevalonate pathway used for prenylation of several low molecular mass G proteins, including Ras.
