We aim to reveal the chemistry of carbon-chain molecules in high-mass star-forming regions from molecular level to chemical evolution, applying the methods established in low-mass star-forming regions. In this proceeding, we summarize the topic about the main formation pathway of HC3N. We carried out observations of three 13C isotopologues of HC3N toward a hot core G28.28-0.36 with the 45-m radio telescope of the Nobeyama Radio Observatory. From the observational results, we propose that the main formation pathway of HC3N is the neutral-neutral reaction between C2H2 and CN. We also compare the results among the different star-forming regions, from a low-mass starless core to a high-mass star-forming core.
