Pierre & Rich -

At one time, I had to perform such testing, but it's too
long ago and was so infrequently necessary that I've lost
all details.  However, I did save one of the tablets in a
35mm film canister.  My note on the outside says
"hexamethylene tetramine C16H12N4," that last bit being the
precise chemical composition.
