My neighbor had a bunch of IMR powder still brand new, in a very warm part of his house. Kept there for 8 years!!!

I was told heat/ warmth will strat to break down the powder.

It would have a unique bad odor/ smell....

Which this does...like a paint thinnner ....

Is it any good ???

I'd have to smell it to make sure, but I think you are probably smelling the solvents that are naturally in the powder.
Decomposing powder gives of a acid like smell that burns my nose. I'll also make the inside of the can rust pretty bad.

sounds good, if kept inside usually good.
