Created a compound unintentionally; any idea on what it is?
Here's the story;
A little 1,3 propanediol (~2mL) was placed into a plastic bottle, along with about 3mL of ~3% H2O2, then I forgot about it.
In a graduated cylinder was left a little (~1mL) solution of tetraaminecopper II sulfate + rubbing alcohol+ NH3 and possibly some Cu(OH)2.
Mistaking the first solution with water, I emptied the contents into the cylinder, immediately forming a grayish-green solution that bubble heavily
and became warm. This is what it looks like:
Any ideas on what I made?
EDIT: It appears that the reaction occurs even if the 1,3 propanediol is removed.

A Fenton oxidation of ammonia and 2-propanol gives mostly nitrogen in the first case, and acetone and its further oxidation products in the second
case. Similarly, the Fenton oxidation of 1,3-propanediol gives a complex mixture of oxidation products.
By the way, you obviously did not create any compound, you just observed reactions with a visible outcome. "Creating" a compound means to synthesize
it, which includes the reaction and isolation of a substance pure enough for a characterization.
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

I am all for experimentation and discovery and wished I had started younger but I think you would accomplish more by getting a beginners text book and
doing some basic reactions as they are written in the text book. With all the literature and simple reactions that will solidify your understanding
why not start there? That is the one thing i feel I did right was read read read read for years before I had the means to do anything, not bashing
just sharing my past 
Maybe I will post this on all of the really amateur questions just because so much of science is recognizing things from a previous experience it is
amazing how easy "chemistry 101" is when you can identify acids and bases. I am being serious, my understanding of chemistry when i was 18 would have
been insane had I had a place like this.

It sounds like the OP was just mixing two waste solutions either to see what happened or just to save space in one container.

You're correct

It leaves behind a material of the same color, but the original solution changed to a light blue color(as opposed to a deep purple-blue color of the
original tetraaminecopper (ii) sulfate solution). The other solutions(both with and without the 1,3 propanediol) have not gained the same color as the
the one described above.

Is it the Philosophers' Stone (blue/green Liquid version) ?
If this is a Test, then i certainly Fail.
It is unlikely that the Best people on this website will even bother to comment, as what you've done is just mix random quantities of different
things.
There is no Plan, no Idea - nothing.
You may as well ask 'What is This ?' when you piss in a bucket of frogspawn.

Aga, I'm sure one of your suggestions is accurate!

Please, please leave out sarcasm. I want to learn from this forum, not be insulted by it.

Fair enough.
You got lucky with Nicodem (one of the best) already telling you what might have happened.
To identify what is in your mixture you'd need very expensive anlysis equipment and most people don't have $500,000 worth of lab gear.
One of the first things to learn is to not just mix up random chemicals hoping to get any useful results.
Pick a chemical you Want to synthesise, find a procedure for that, then follow that procedure and see what the result is.
If it fails, then many people here will be willing & able to help you learn.
E.g. try making pure tetrachlorocuprate CuCl4 crystals from your copper sulphate and some NaCl.
CuCl4 might not be a sexy chemical to make, however you'll need a couple of important practical skills to achieve it.

Nitpick. You missed the charge.
(And I get to cite our very own wiki that I have been reading a bit lately.)
