Crotoxyphos properties
Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.

Further notes on Crotoxyphos
These are descriptions rather than measured values, so they are kept out of the table above and quoted here with the source that reported them.
Corrosivity
Slightly corrosive to copper, lead, mild steel, tin and zinc, but will not attack fiberglass, reinforced polyester, rigid PVC, or the usual lacquers used for lining drums. Incompatible with most mineral carriers, except synthetic silicas such as 'Colloidal Silica K320' and 'Hisil 233'.
