CAS 127-19-5 Dimethylacetamide (DMAC), chemically known as N,N-Dimethylacetamide, is a high-purity polar aprotic solvent widely used in pharmaceutical synthesis, polymer processing, coatings, and electronic chemicals.
N,N-Dimethylacetamide (DMAc) is a high-performance polar aprotic solvent. It has strong dissolving power and can dissolve many organic and inorganic compounds, polymers like spandex and aramid fibres, as well as pharmaceuticals. DMAc is also thermally and chemically stable, boils at 165°C, and mixes completely with water and common organic solvents.
Chemical Name: N,N-Dimethylacetamide
CAS Number: 127-19-5
Molecular Formula: C₄H₉NO
EC Number: 204-826-4
Core Advantages as a Solvent
Dimethylacetamide DMAc's greatest strength is its exceptional solvency. It can dissolve polymers, resins and pharmaceutical active ingredients that many other solvents cannot, which is essential for making polyacrylonitrile, polyurethane and aramid fibres. Its polar aprotic nature speeds up sensitive nucleophilic reactions, such as those in drug synthesis, as it has no acidic protons to inactivate reagents. Thanks to its high boiling point and stability, it works well in high-temperature processes, boosting reaction efficiency and yields. It is also versatile, used in pharmaceuticals, electronics, coatings and adhesives.
