Ethyl formate - ethyl ester of formic acid, chemical formula - . German scientists from the Institute of Planck argue that this connection, they found in the gas-dust cloud Sagittarius B2 using a thirty- meter radio telescope IRAM , gives the characteristic smell of the forest raspberry [9] . Russian chemists do not confirm this fact [10] .
