About DMF
[DMF] is a powerful, versatile organic solvent widely used in industrial and laboratory settings. It is often referred to as a "universal solvent" because it can dissolve both organic and inorganic substances.
Safety
*Gloves: DO NOT use thin Nitrile or Latex. DMF permeates them in minutes. Use Butyl Rubber or Viton gloves. For maximum safety, use multi-layer laminate gloves (like Silver Shield).
* Eye Protection: Chemical splash goggles are mandatory. A face shield is recommended if you are pouring large volumes.
* Clothing: A chemical-resistant apron should be worn to prevent spills from soaking into fabric and staying against the skin.
Storage
DMF is an aggressive solvent that can dissolve or soften many plastics and rubbers.
* Recommended: Stainless steel, glass (for small quantities), or high-density polyethylene (HDPE) containers specifically rated for solvents.
* Avoid: Aluminum, copper, and their alloys. DMF can cause corrosion in these metals over time, especially if moisture is present.
* Gaskets/Seals: Use PTFE (Teflon) or FKM (Viton) seals. Standard rubber or neoprene gaskets will degrade and leak.
2. Environmental Conditions
* Cool & Dry: Store in a cool, well-ventilated area away from direct sunlight. High temperatures increase vapor pressure and the risk of container bulging.
* Hygroscopic Nature: DMF "pulls" moisture out of the air. If the container is left open, it will absorb water, which ruins the purity and can make the chemical more corrosive to storage tanks.
