Benzoquinone is quite insoluble and has an intense color and odor. The odor is so strong it cannot be ignored or missed.

Testing is probably the only way to examine this. Testing by development, that is.

Sorry, these cross test with various homebrews take really more time than I have actual, a nightshift week on work is just coming.
But there is a strange odor at the last 2 samples, somehow, how to describe, like a (smashed) ladybug…

You can run those tests with B&W film and short development times. Comparisons are possible that way.
