We selected the molecular region towards IRAS 18236-1205 source, for the purpose of studying the stellar population and define embedded young stellar objects (YSOs). We selected the molecular region using the Galactic Ring Survey (GRS) in ^{13}CO and observations of high-density molecular gas, CS. The IRAS 18236-1205 source has IR colors as an Ultra Compact HII region. That makes this region a good candidate to investigate massive star formation. To study the stellar component we used point source catalogues in the near (2MASS), middle (MSX/Spitzer) and far infrared (IRAS), respectively. From the color-color and color-magnitude diagrams with 2MASS and IRAC-SPITZER data, we developed a photometric criterion to identify embedded YSOs in the molecular region. Applying a model to the spectral energy distribution (SED) of some objects, we have noted that the best fitting are for those models of young stellar objects embedded in its progenitor envelope. This photometric analysis allowed us to select embedded YSOs of massive, medium and low mass in the molecular region, as well as their precursors (dense molecular cores, Infrared Dark Clouds) and effects on the interstellar medium (HII regions and objects associated with outflows, HH objects). Spectroscopy and observations on narrow band photometry (Brγ, [FeII]) and molecular lines (H_2) are future work that will support our selection.
