FAQ - Technical & Supply Chain
-
Q:
Are DMF and N,N-Dimethylformamide the same solvent?
A: Yes. N,N-Dimethylformamide and DMF identify CAS 68-12-2. They are not the same as dimethylacetamide (DMAc), N-methyl-2-pyrrolidone (NMP) or dimethylformamide dimethyl acetal. State the full name, CAS number and solvent grade in the purchasing specification. -
Q:
Which specifications matter when purchasing industrial DMF?
A: Agree assay by gas chromatography, water, color, acidity or alkalinity, nonvolatile residue, iron and other trace metals where relevant. Electronics, polyurethane and pharmaceutical processes may require different impurity limits. The quotation should identify the test methods, packaging and batch COA basis rather than only a purity percentage. -
Q:
What should be confirmed before bulk DMF delivery?
A: Confirm container compatibility, seals, ventilation, grounding, quantity, previous cargo and unloading arrangement. Review the current SDS and occupational-exposure controls for the destination site. Keep the solvent closed and protected from contamination, and verify whether the process requires a low-water or low-metal grade.
