Abstract: The recent availability of wideband receivers and high sensitivityinstruments in the mm and submm wavelengths has opened the possibility ofstudying in detail the chemistry of the interstellar medium in extragalacticobjects. Within the central few hundred parsec of galaxies, we find enormousamounts of molecular material fueling a wide variety of highly energetic eventsobserved in starbursts galaxies undergoing an intense burst of star formationand active galactic nuclei AGN, where activity is driven by the accretion ofmaterial onto the nuclear black hole.Here it is presented a brief summary of both the history and the latestresults in observational chemistry in distant galaxies. It will be shown howthe molecular emission, is a powerful tool to explore the physics of thedust-enshrouded, buried nuclei of distant ultraluminous galaxies, which areheavily obscured at other wavelengths. Special attention will be given to thepossibilities offered by next generationinstruments such as ALMA Atacama LargeMillimeter Array, expected to have a vast impact on the field of ExtragalacticChemistry. Molecular studies in the early Universe will become available atunprecedented sensitivity and resolution.
