  We analyze the molecular gas and dust associated with the infrared dark cloud
SDC 341.232-0.268 in order to investigate the characteristics and parameters of
the gas, determine the evolutionary status of four embedded EGO candidates and
establish possible infall or outflow gas motions. We based our study on
$^{12}$CO(2-1), $^{13}$CO(2-1), and C$^{18}$O(2-1) data obtained with the APEX
telescope, molecular data of high density tracers from the MALT90 survey and IR
images from Spitzer, Herschel and ATLASGAL. The study reveals two clumps at -44
km/s towards the IRDC, with densities of > 10$^4$ cm$^{-3}$ , typical of IRDCs,
while high density tracers show H$_2$ densities > 10$^5$ . FIR images reveals
the presence of cold dust linked to the molecular clumps and EGOs. A comparison
of spectra of the optically thin and optically thick molecular lines towards
the EGOs suggests the existence of infall and outflow motions.
