The superior alternative to HMPA for challenging syntheses:

• HMPA Replacement: Offers similar solvating power for cations but with significantly lower toxicity, making it safer for industrial scale-up.

• Reaction Promoter: Accelerates nucleophilic substitution reactions (SN2) involving inorganic salts (e.g., fluorination, cyanation) due to its high dielectric constant.

• Electronics Grade: Used as a high-performance solvent for electrolytes and photoresist stripping due to its chemical and thermal stability.

• Polymer Processing: Excellent solvent for high-performance polymers like polyamides and polyimides.

Packaging: 200kg Plastic/Iron Drum or 1000kg IBC.

Storage: Hygroscopic. Store in a cool, dry place under nitrogen atmosphere if possible.
