Description

Dimethylformamide is an organic compound with the formula (CH3)2NC(O)H. Commonly abbreviated as DMF (although this acronym is sometimes used for dimethylfuran, or dimethyl fumarate), this colourless liquid is miscible with water and the majority of organic liquids. DMF is a common solvent for chemical reactions. Dimethylformamide is odorless whereas technical grade or degraded samples often have a fishy smell due to impurity of dimethylamine. As its name indicates, it is a derivative of formamide, the amide of formic acid. DMF is a polar (hydrophilic) aprotic solvent with a high boiling point. It facilitates reactions that follow polar mechanisms, such as SN2 reactions.

10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

DMF is stable. It is hygroscopic and easily absorbs water form a humid atmosphere and should therefore be kept under dry nitrogen. High purity DMF, required for acrylic fibers, is best stored in aluminum tanks. DMF dose not change under light or oxygen and does not polymerize spontaneously. Temperatures >350°C may cause decomposition to form dimethylamine and carbon dioxide, with pressure developing in closed containers.

10.3 Possibility of hazardous reactions

CombustibleN,N-DIMETHYLFORMAMIDE may react violently with a broad range of chemicals, e.g.: alkaline metals (sodium, potassium), azides, hydrides (sodium borohydride, lithium aluminum hydride), bromine, chlorine, carbon tetrachloride, hexachlorocyclohexane, phosphorus pentaoxide, triethylaluminum, magnesium nitrate, organic nitrates. Forms explosive mixtures with lithium azide [Bretherick, 5th ed., 1995, p. 453]. Oxidation by chromium trioxide or potassium permanganate may lead to explosion [Pal B. C. et al., Chem. Eng. News, 1981, 59, p. 47].

Acute toxicity

  • Oral: LD50 Mouse oral 6.8 mL/kg
  • Inhalation: LC50 Mouse inhalation 9400 mg/cu m/2 hr
  • Dermal: no data available

Skin corrosion/irritation

no data available

Serious eye damage/irritation

no data available

Respiratory or skin sensitization

no data available

Germ cell mutagenicity

no data available

Carcinogenicity

Evaluation: There is inadequate evidence in humans for the carcinogenicity of dimethylformamide. There is evidence suggesting the lack of carcinogenicity of dimethylformamide in experimental animals. Overall evaluation: Dimethylformamide is not classifiable as to its carcinogenicity in humans (Group 3).

Reproductive toxicity

Only one study is available on the reproductive effects of dimethylformamide in humans. This study reported an increased rate of spontaneous abortion among pregnant women occupationally exposed to dimethylformamide. However, these results cannot be attributed solely to dimethylformamide, as these women were exposed to a number of additional chemicals. Dimethylformamide is embryotoxic in animals; reduced implantation efficiency, decreased mean fetal weight, and increased abortions have been reported in rats exposed by inhalation. In rabbits exposed to dimethylformamide by gavage (experimentally placing the chemical in the stomach), decreased mean fetal weight and increased percentage of malformed live fetuses per litter and increased percentage of litters with malformed fetuses were observed in the high-dose group.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: /Oncorhynchus mykiss/ (rainbow trout) weight 0.8 g; Conditions: static bioassay; Concentration: 12,000 mg/L for 96 hr (95% confidence limits 10,000-13,000 mg/L)
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea) age <24 hr; Conditions: freshwater, static, 20.5°C, pH 7.04-7.97, hardness 46.4 (40.4-56.3) mg/L CaCO3, alkalinity 41.7 (30.0-46.0) mg/L CaCO3, dissolved oxygen 85.5 (77.5-90.8) mg/L; Concentration: 26300000 ug/L for 24 hr (95% confidence interval: 23400000-29600000 ug/L); Effect: intoxication, immobilization
  • Toxicity to algae: EC50; Species: Anabaena inaequalis (Blue-Green Algae) 1X10+6 cells/mL; Conditions: freshwater, static; Concentration: 0.6% for 10-14 days (95% confidence interval: 0.36-0.84%); Effect: growth, general /formulation
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Aerobic unacclimated and acclimated river die-away tests showed that N,N-dimethylformamide at an initial concentration of 30 mg/L completely disappeared within 6 and 3 days, respectively(1). However, 24 to 48 hours was required before any degradation was observed among unacclimated samples(1). N,N-Dimethylformamide, present at 100 mg/L, reached 4.4% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(2). Aerobic grab sample data for N,N-dimethylformamide in sea water showed a mineralization rate of <3% in 24 hours for initial concentration of 10 ug/L and 100 ug/L(3). However, 20% of N,N-dimethylformamide at a concentration of 0.1 ug/L was mineralized in 24 hrs(3). All samples were adjusted to sterilized controls(3). Aqueous screening test data demonstrated that dimethylformamide was easily removed by sewage treatment facilities upon acclimation(4). Wastewater from a polyimide synthesis operation at Kansas City, MO contained N,N-dimethylformamide at a concentration of 65,500 mg/L before entering a bench scale biological treatment system(5). At feed rates of 90 lb/day/1000 cu ft, effluent from the biological reactor contained N,N-dimethylformamide at a concentration of <10 mg/L(5). The concentration of N,N-dimethylformamide in the reactor sludge was not documented(5).

12.3 Bioaccumulative potential

BCFs of 0.3-1.2 and 0.3-0.8 were reported in carp (Cyprinus carpio) when exposed to 2 and 20 ppm of N,N-dimethylformamide over a 2-week period, respectively(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of N,N-dimethylformamide can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that N,N-dimethylformamide is expected to have very high mobility in soil.

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.
