Contextualization of the prebiotic roles of cyanamide and carbodiimide. Panel A: processes in the ISM, including the formation of cyanamide and carbodiimide explored in this work. Panel B: fate of cyanamide in planetary conditions. Cyanamide directly formed in planetary atmospheres, or in the ISM and delivered to a planet after accretion, could lead to a rich diversity of organic compounds or intervene as condensing agents in the formation of organophosphates. Panel C: processes that may take place in both the ISM and in planetary environments.
