CAS 80-73-9 corresponds to 1,3-dimethyl-2-imidazolidinone (DMI), which is a highly polar, low toxicity non proton solvent and important pharmaceutical/chemical intermediate.

Core Information
-Chinese name: 1,3-dimethyl-2-imidazolidinone (alias: dimethylethenylurea, N, N ‘- dimethylethyleneurea)
-English name: 1,3-Dimethyl-2-imide (DMI, DMEU)
-Molecular formula/molecular weight: C ₅ H ₁₀ N ₂ O/114.15
-Appearance: Colorless, transparent, low viscosity liquid with a weak odor of fatty amines
-Key physicochemical parameters: melting point 8.2 ° C, boiling point 225.5 ° C, density approximately 1.044-1.056 g/mL (25 ° C), flash point 93-120 ° C, refractive index~1.472
-Solubility: miscible with water and most organic solvents (ethanol, acetone, etc.), insoluble in petroleum ether; Strong acid and alkali resistance, good thermal stability

main purpose
1. Organic synthesis solvent: As a green substitute for HMPA, it is used for nucleophilic substitution, reduction, oxidation, and coupling reactions (such as Ullmann reaction).
2. Polymer industry: polymerization solvents for polymers such as polyamide to improve the mechanical and thermal properties of materials.
3. Medicine and Fine Chemicals: Used as a drug transdermal absorption promoter, intermediate for pesticide/dye/liquid crystal material synthesis, and electrolyte additive.
4. Other applications: electronic component cleaning agents, inkjet ink solvents, and formaldehyde capture agents.

Safety and Storage
-Toxicity characteristics: Extremely low toxicity, but irritating. Avoid inhalation or skin contact.
-Storage conditions: Dry and sealed storage, easy to absorb moisture, keep away from sources of fire and oxidants.
