One example of an obstacle I encountered during the excitation of a project in my undergraduate pharmaceutical research laboratory would be that the inventory of essential chemicals was not up to date with the computer log. Often times, while preforming multistep organic synthesis, a critical solvent or solute would be missing or even the container empty with nobody bothering to order more. This would cause time delays in the production of the final pharmaceutical compound in relation to its expected completion date due to the need to stop manufacture and order from an outside vendor the missing component and wait for delivery. The delay became an issue that could have easily been prevented if a more careful inventory of starting materials had been done prior to starting the chain of reactions. Lucky, the lead professor had built in enough slack time into the project schedule that the delay of some compounds did not through off the entire study.
