Pyrogallol

Anyone know the shelf life of Pyrogallol (raw chem)?
My search was fruitless.
Cheers

Seems to last a long, long time.

Mine's about ten years old and still working fine...

I've used some that's at least 40 years old, and it performs identically to some that I fresh pyrogallol that I bought recently.

As long as it's not getting dark brown, it should work fine. (My old stuff is a light tan color.)

Thats great, thanks.
