What is N,N-Diethylformamide CAS 617-84-5?

N,N-Diethylformamide is a polar aprotic amide solvent with the molecular formula C5H11NO and a molecular weight of about 101.15 g/mol. It is a colorless to nearly colorless liquid used mainly in specialty chemical synthesis and industrial solvent systems.

What are the main industrial uses of N,N-Diethylformamide?

It is used as a specialty solvent, reaction medium, and extractant in fine chemical processing. Applications also include crystal and MOF synthesis, lithium-ion battery solvent research, LCD panel cleaning, paint stripping, and selected pigment or coating formulations.

What are the typical physical properties of CAS 617-84-5?

N,N-Diethylformamide is a clear liquid with a boiling point around 176-178 deg C, density about 0.908 g/mL at 25 deg C, and refractive index about 1.434. It is miscible with water and many organic solvents and has a flash point commonly cited around 60 deg C.

What purity or grade is available for industrial procurement?

Commercial supply commonly includes technical grade and high-purity material with purity around 99% or higher. The appropriate grade depends on whether the material is used for general synthesis, specialty solvent applications, or more tightly controlled process work.

N,N-Diethylformamide (DEF) CAS 617-84-5

N,N-Diethylformamide, commonly abbreviated DEF, CAS 617-84-5, is a low-molecular-weight liquid amide supplied as a specialty solvent and synthesis-use chemical for fine chemical processing and controlled solvent systems.

Product Description

N,N-Diethylformamide (DEF) CAS 617-84-5 is a polar aprotic amide solvent, with EC 210-533-2 and molecular formula C5H11NO.

Synonyms: Diethylformamide; N-Formyldiethylamine; Formyldiethylamine; Formic Acid Diethylamide; DEF.

CAS: 617-84-5.

Molecular formula: C5H11NO.

It has a molecular weight of about 101.15 g/mol.

It is supplied as a colorless to nearly colorless liquid.

It has a boiling point around 176-178 C and a density of about 0.908 g/mL at 25 C.

It is positioned as a specialty solvent and synthesis-use chemical rather than a broad-volume commodity solvent.

It is used as a specialty solvent and reaction medium in fine chemical processing.

It is used as an extractant and in selected specialty reaction systems.

Applications include crystal and MOF synthesis, lithium-ion battery solvent research, LCD panel cleaning, paint stripping, and selected pigment or coating formulations.

It is miscible with water and many organic solvents and is a flammable liquid.

Confirm the required grade, purity, appearance, water content, and related specifications for the chosen grade.

Store in tightly sealed original containers in a cool, dry, well-ventilated area, away from direct sunlight, heat, and ignition sources.

Because it is a flammable liquid, use appropriate PPE and avoid prolonged exposure to air and moisture, and keep it away from incompatible materials.

Confirm packaging suitable for the liquid form and order quantity, and follow the current SDS.

Confirm grade, packaging, and specification as required.
