The past decades have revealed that planets are incredibly common, and incredibly diverse. The origins of planets and their compositions are intimately linked to the chemical environments within which planets assemble, i.e. to the chemistry of planet-forming disks. The arrival of ALMA has provided observational access to disk chemistry, revealing disk snowlines, abundant organic molecules, and curious chemical gradients and sub-structures across the planet and comet forming zones. The most recent development is the execution of the ALMA Large Program MAPS (Molecules with ALMA on Planet-forming Scales), which has enabled us to zoom in on disk chemical structures at scales of 10-30 au. In parallel to these observational developments, astrochemistry models and laboratory experiments are providing new clues on what chemistry is likely to occur in different disk environments. I will present highlights from the MAPS program, as well as some recent laboratory astrochemistry discoveries. I will discuss how these new observational and laboratory data are affecting our understanding of the chemistry of planet formation, the chemical habitability of mature planetary systems, and the history of our own Solar System.
