This is from the paper, All the COSAC organics can be formed by UV irradiation and/or radiolysis of ices due to the incidence of galactic and solar cosmic rays: alcohols and carbonyls derived from CO and H2O ices (19), and amines and nitriles from CH4 and NH3 ices (20). Hydrolysis of nitriles produces amides, which are linked to isocyanates by isomerization. "Organic" only means "made of C,H,O,N", and doesn't imply biology. (But these are actually pre-biotic chemicals, which is why it's very interesting).
