Mission 6: Outbreak
You will come to the room with the blueprint during the mission. You will have to get the keycard from here.
Once you have crafted the molotov cocktail you have to throw it at the alien and it will retreat. A good spot is the next area that you access with the keycard. A human enemy will be there and he starts shooting if you get close to him. The alien will then come to his position and attack him. At this point you have enough time to aim and throw the molotov at the alien.
