Appearance:Liquid
Melting Point:Decomposes without melting
Boiling Point:120.3ºC at 760mmHg
Flash Point:26.6ºC
Water Solubility:H2O: 72.2 g/100 mL at 20 ºC
Storage Conditions:APPROX -18°C
Vapor Pressure:Non-volatile
Toxicity:Oral-Rat LD50: 450 mg/kg; Oral-Mouse LD50: 50 mg/kg
Flammability characteristics:Combustion produces toxic sulfur oxide gas
Experimental Properties:Colorless crystals. /Dihydrate/|IN DIL AQ SOLN, AT PH 9.5, VAPAM DECOMPOSES TO METHYL ISOTHIOCYANATE AND SULFUR; UNDER ACID CONDITIONS, CARBON DISULFIDE, HYDROGEN SULFIDE, N,N'-DIMETHYLTHIURAM DISULFIDE, METHYLAMINE, METHYL ISOTHIOCYANATE ARE FORMED.|A soil fungicide, nematocide, & herbicide reputed to act by decomposition in moist soil to methyl isothiocyanate. If true, this may be a unique property of metham, as opposed to many closely related chemicals used for much of the same purposes, eg, ferbam, nabam, ziram, zineb, & maneb.
Air and Water Reactions:Slow reaction upon dilution produces toxic gases hydrogen sulfide and methylisothiocyanate. This reaction is accelerated by the addition of acid.
Reactive Group:Thiocarbamate Esters and Salts/Dithiocarbamate Esters and Salts
Reactivity Alerts:Water-Reactive
Reactivity Profile:METAM SODIUM is a dithiocarbamate. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides. It will decompose upon dilution to carbon disulfide, monomethylamine, methylisothiocyanate, and hydrogen sulfide. The decomposition products are flammable and toxic. The acute symptoms of exposure to metam sodium are excessive salivation, sweating, fatigue, weakness, nausea, headache, dizziness, eye and respiratory tract irritation, and skin irritation in the form of rashes. The spillage of a rail car tanker of metam sodium into the Sacramento River caused a major fish kill (over a million trout) along several miles of that river.
Flammable Limits:Non flammable. /Metham Sodium Dihydrate/
Corrosivity:THE AQUEOUS SOLUTION IS CORROSIVE TO BRASS, COPPER AND ZINC|Aluminum, very rapid corrosion; mild steel, 0.7 mg/day/sq m; stainless steel, <0.2 mg/day/sq m
