Tehran has previously accused Syrian rebels of being behind what it called suspected chemical attacks.
Rouhani did not mention the international furore around Syrian opposition reports that government forces had killed as many as 1,000 civilians with gas in Damascus on Wednesday.
"Many of the innocent people of Syria have been injured and martyred by chemical agents and this is unfortunate," recently elected Rouhani was quoted as saying by the ISNA news agency.
"We completely and strongly condemn the use of chemical weapons, because the Islamic Theocratic
Republicof Iran is itself a victim of chemical weapons," he said, according to the agency.
Iran suffered chemical weapons attacks by Iraqi forces during the 1980-1988 Iran-Iraq war.
"The Islamic Theocratic
Republicgives notice to the international community to use all its might to prevent the use of these weapons anywhere in the world, especially in Syria," Mehr news agency quoted Rouhani as saying.
Syria's government denies using such weapons and Iran's foreign minister said on Thursday that groups fighting Assad's forces in a two-year-old rebellion must have been behind what he then said was just a suspected gas attack.
