We present molecular line observations of the massive star forming regionIRAS 17233-3606 aimed at studying the molecular core associated with thesource. The observations were made using the Atacama Pathfinder Experimenttelescope in the CO (3-2) and HCO^+ (4-3) transitions, and in the CH_3OH(6_K-5_K), (7_K-6_K) and CH_3CN (16_K-15_K) bands. For the CO(3-2) and HCO^+(4-3) transitions, we obtained maps with a size of 70''\times 70''. The typicalangular resolution of the data is ~18''. Our observations reveal anexceptionally rich molecular spectrum, a signpost of hot core activity.Comparisons with two other prominent southern hot cores were made throughobservations in the same frequency setups. We also detected a bipolar outflowin CO (3-2) and HCO^+ (4-3) lines. Modelling reveals a hot core of size ~3''and a temperature of 150 K in the IRAS17233-3606 region. The parameters of themolecular outflow are derived through the analysis of the CO (3-2) emission,and are typical of outflows driven by high-mass young stellar objects.
