Carbonaceous chondrites (CCs) can be considered cosmic aggregates containing protoplanetary disk components. Modern analytical techniques allow us to identify CCs unaffected by thermal or aqueous alteration processes, having a pristine nature. Such a highly unequilibrated meteorites allow us to get clues on the early Solar System (ESS), as their components are ancient materials retentive of chemical clues on their formation. The information they contain is valuable to be applied to better understand protoplanetary disks.
