Description of key information
Additional information
Physical state: Formamide is a slightly viscous, colourless liquid which is odourless or at industrial grade with a faint odour of ammonia.
Melting point: 2.6 °C
Boiling point: 218.3 °C (decomposition starts above 140 °C)
Density: 1.13 g/cm³ at 20 °C
Particle size distribution: Formamide is marketed and used as liquid.
Vapour pressure: 0.06 hPa at 20 °C
Partition coefficient: -0.82 at 25°C
Water solubility: 1E06 mg/L at 25 °C
Surface tension: Based on the chemical structure, no surface activity is expected.
Flash point: 152 °C at 1013 hPa
Auto flammability: > 500 °C
Flammability: Not flammable; based on the molecular structure and experience in use formamide has no pyrophoric properties; it does not react with water under formation of flammable gases.
Explosiveness: Not explosive; Examination of the structure indicates that there are no groups associated with explosive properties.
Oxidising properties: Not oxidising; due to the structural composition of the substance it is not considered to be oxidising.
Stability in organic solvents and identity of relevant degradation products: In accordance with column 1 of Annex IX, the study does not need to be conducted if the stability of the substance is considered to be critical. Formamide is not considered as critical.
Dissociation constant: pKa at 20/25°C: -0.48
Viscosity: 3.764 mPa*s at 20 °C
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
