| Hazard Information | Back Directory | [Chemical Properties]
Nearly colorless liquid. Insoluble in water; soluble in a variety of organic
solvents. | [Uses]
Organophosphate pesticide used in the agriculture industry | [General Description]
Emulsifiable oil. | [Reactivity Profile]
Organothiophosphates, such as MERPHOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. | [Hazard]
Cholinesterase inhibitor. | [Environmental Fate]
Merphos is adsorbed strongly to soil and oxidized to
S,S,S-tributyl phosphorotrithioate (DEF). The Koc estimated for
merphos is theoretically 62 000; accordingly, merphos would
be immobile in soil.
In water, merphos will be oxidized to DEF. The fact that
merphos is expected to adsorb strongly to particulate matter in
the water column, apparently did not impede its oxidation.
In the atmosphere, merphos will exist as an aerosol and be
removed by gravitational settling and readily oxidized to DEF.
Vapor-phase merphos will react with photochemically
produced hydroxyl radicals, with an estimated half-life of 4.9 h. |

III | [Safety Profile]
Poison by
intraperitoneal route. Moderately toxic by
ingestion and skin contact. A cholinesterase
inhibitor. Combustible when exposed to
heat or flame. Can react vigorously with
oxidzing materials. When heated to
decomposition it emits highly toxic fumes of
POx and SOx. Used as a defoliant. See also
