Chemistry - Part 2 Tarkov: Quest help

I'm already tired of waiting. The documents you retrieved from that humanoid's lair are valuable, and not just a little. But it's dangerous merchandise. And there's no telling who the best buyer might be. And it's not even about the profit, it's about the huge fucking problems if we choose the wrong recipient. Here's the key you found there too, try digging around. My men told me it came from a dormitory. And judging by the documents, the deputy chief was seen on the second floor of the first building, the one with three levels. Any information you can find in this room will be very useful, and the reward will be considerable.
