PZ can coordinate through the pyrazine
ring nitrogen and its strong hydrogen bonding ability along with its ability to act as ligand in multiple complexes with transition metals makes it a potential candidate for the synthesis of various highly organized and distinct coordination polymers [16-19].

The HOMA indices calculated for pyrrole (1), 3,4-dihydropyrrolopyrazinones (1a-c), pyrazine
(1d), 2-oxopyrazine (1e), and pyrrolopyrazinones (2-22) are shown in Table 1.
In the present study, heterocyclic compounds were also identified, including 9 pyrazines
and 1 furan.
Other substances, such as menthol (42.9 per cent of samples), ethyl vanillin (16.5 per cent of samples) and acetyl pyrazine
(8.2 per cent of samples), are classified as "able to cause respiratory irritation".
