How to Solve the Chemical Agents Puzzle in Directive 820

First, look at the Diazepam Synthesis display, which features the many different chemical structures that will need to be combined so you can get the correct code. Right now, all you have are the chemical symbols above, so try to remember them as best you can. There are three in total..



Around the room are a bunch of posters or boards on the wall. Every one of them contains three chemicals followed by their associated symbol. Remember the symbols on the Diazepam Synthesis display. You need to figure out the names of those three chemicals on that display.
After looking at the three boards, you will discover the three chemicals are Chloroacetyl Chloride, Ammonia, and Dimethyl Sulfate. Now that you have the names of those three chemicals, you can go over to the storage cabinet to figure out the proper code!

Each of those three chemicals has a number associated with it. Find the Chloroacetyl Chloride, Ammonia, and Dimethyl Sulfate (in that order) and the corresponding number that goes along with them. The code will be: 168.
Go over to the locked cabinet and punch in the code, which will combine these three chemicals. Once it opens, Cooper will be able to get her hands on the sedative. You need the sedative because it is the only way to sedate Mr. Williams.
Once you figure out the names of the three chemicals in the Diazepam Synthesis display, it is pretty easy to figure out the code over at the storage cabinet containing all the chemicals.
