Product Description
N,N-Dimethylformamide (DMF) is a polar aprotic formamide solvent identified by CAS 68-12-2 and EC/EINECS 200-679-5.
Synonyms: DMF; Dimethylformamide; N,N-Dimethylformamide; N-Formyldimethylamine.
CAS: 68-12-2.
Molecular formula: C₃H₇NO.
Molecular weight: 73.09 g/mol.
EC number: 200-679-5.
It is a clear, colorless to pale-yellow hygroscopic liquid with a slight amine odor.
DMF is miscible with water and many organic solvents, giving it broad solvent power.
It is mainly used as a solvent in polymer and chemical manufacturing: polyurethane synthesis for synthetic leather, coatings, elastomers and adhesives, acrylic-fiber dry spinning, pharmaceutical and peptide synthesis, and agrochemical processing.
It is also used in reactions such as Vilsmeier-Haack formylation and in surface-coating or electronic-cleaning processes.
Confirm assay, water, dimethylamine or amine content, acidity or alkalinity, color, and evaporation residue for the intended process.

FAQ - Technical & Supply Chain
-
Q:
What is N,N-Dimethylformamide (DMF) CAS 68-12-2?
A: N,N-Dimethylformamide, commonly abbreviated DMF, is a polar aprotic solvent with CAS 68-12-2 and molecular formula C₃H₇NO. It is a clear, colorless to pale-yellow hygroscopic liquid with a slight amine odor. DMF is miscible with water and many organic solvents, which gives it broad solvent power. -
Q:
What is DMF mainly used for?
A: DMF is mainly used as a solvent in polymer and chemical manufacturing. Major applications include polyurethane synthesis for synthetic leather, coatings, elastomers, and adhesives; dry spinning of acrylic fiber; pharmaceutical and peptide synthesis; and agrochemical processing. It is also used in reactions such as Vilsmeier-Haack formylation and in surface-coating or electronic-cleaning processes. -
Q:
What grades and typical properties should be confirmed?
A: Common commercial and analytical grades are around 99.8% or higher, with some high-purity grades at 99.9% by GC. Typical properties include a melting point near -61 °C, boiling point near 152-153 °C, density about 0.944-0.949 g/mL, and complete water miscibility. Confirm assay, water, dimethylamine or amine content, acidity or alkalinity, color, and evaporation residue for the intended process. -
Q:
How should DMF be stored and handled?
A: Store DMF in tightly closed, compatible containers in a cool, dry, ventilated area away from heat, ignition sources, strong oxidizers, and incompatible acids or bases. Protect it from moisture ingress because the liquid is hygroscopic. Use appropriate PPE, bonding and grounding, and normal solvent-handling controls when transferring or processing DMF.
