Description

N-Methylformamide (NMF) is a colorless, nearly odorless, organic compound with molecular formula CH3NHCHO, which is a liquid at room temperature. It is infinitely soluble in water. NMF is mainly used as a reagent in various organic syntheses with limited applications as a highly polar solvent.
NMF is closely related to other formamides, notably formamide and dimethylformamide (DMF). However, industrial use and production of NMF are far less than for either of these other formamides. DMF is favored over NMF as a solvent due to its greater stability. Annual production of NMF can be assumed to be significantly less than the production of either formamide (100,000 tons) or DMF (500,000 tons).

Absorption, Distribution and Excretion

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.

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 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).

12.3 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).

12.4 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).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

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.

Contaminated packaging
