Abstract We present a multi-line study of the massive star-forming region IRAS 22506+5944.A new 6.7GHz methanol maser was detected. 12CO, 13CO, C18O and HCO+J = 1 − 0 transition observations reveal a star-formation complex consisting mainly of two cores. The dominant core has a mass of more than 200M⊙, while the other one is only about 35M⊙. Both cores are obviously at different evolutionary stages. A 12CO energetic bipolar outflow was detected with an outflow mass of about 15M⊙.
