Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound include irritation of the mucous membranes and upper respiratory tract. Other symptoms include liver damage, eye irritation with discomfort, tearing or blurring of vision, skin irritation with discomfort or rash, abnormalities of liver function with jaundice, temporary nervous system depression with anesthetic effects such as dizziness, headache, confusion, incoordination and loss of consciousness. ACUTE/CHRONIC HAZARDS: This compound may be absorbed through the skin and cause skin irritation. It may also irritate the eyes, mucous membranes and upper respiratory tract. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and nitrogen oxides. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
8 healthy male subjects were exposed to dimethylformamide vapor at a concn of 8.79 + or - 0.33 ppm for 6 hr/day for 5 consecutive days. All urine voided by the subjects was collected from the beginning of the first exposure to 24 hr past the end of the last exposure & each sample was analyzed for monomethylformamide. Monomethylformamide was rapidly eliminated from the body with urine values peaking within a few hr following the end of each exposure period. The mean for the 7 hr (end of exposure) sample was 4.74 ug/ml urine or 736.8 ug.

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on burning. This produces nitrogen oxides. Reacts with strong oxidants. Attacks some forms of plastic and rubber.
Chemical stability
Solution: A 25% aqueous solution is stable at room temperature for at least one week (NMR).
Possibility of hazardous reactions
A very dangerous fire hazard when exposed to heat or flame.N-METHYLFORMAMIDE is incompatible with benzene sulfonyl chloride. It is also incompatible with strong oxidizing agents, acids, bases and acid chlorides. It may react with chlorine, bromine, nitrates, nitric acid, triethylaluminum, potassium permanganate, chromic acid, chromic anhydride, chromium trioxide, borohydrides, hydrides, thionyl chloride, metallic sodium, phosphorus trioxide, diborane, (octafluoroisobutyrate + sodium nitrite) and (perchloryl fluoride + potassium methyl 4,4-dinitrobutyrate).

Persistence and degradability
AEROBIC: N-Methylformamide, present at 400 mg/l, reached 4%, 98%, and 100% of its theoretical BOD in 3 hrs, 3 days, and 7 days, respectively, using an industrial activated sludge inoculum and the Zahn-Wellens test(1). Using the BOD test, N-methylformamide achieved 2% of its theoretical BOD after 5 days(1). N-Methylformamide has also been shown to biodegrade by microorgansism obtained through soil enrichment(2). Therefore, N-methylformamide may biodegrade in the environment(SRC).
Bioaccumulative potential
An estimated BCF of 3 was calculated for N-methylformamide(SRC), using a log Kow of -0.97(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of N-methylformamide is estimated as 7(SRC), using a log Kow of -0.97(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that N-methylformamide is expected to have very high mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
