Description

Nsc 91800 CAS NO 13560-91-3 is a high-purity chemical compound, also known as 1,3-Dimethyl-2-imidazolidinone (DMI), valued for its exceptional properties as a powerful, aprotic polar solvent. This compound matters for its high thermal stability, low toxicity, and excellent solvating power for a wide range of organic and inorganic substances, making it a superior alternative to traditional solvents. It is primarily needed by industries involved in pharmaceuticals, agrochemicals, polymers, and specialty chemical synthesis where a high-performance reaction medium is critical.

Application

• Pharmaceutical Synthesis: Used as a reaction solvent and solubilizing agent in the production of active pharmaceutical ingredients (APIs), particularly for reactions requiring high temperatures and inert conditions.
• Agrochemical Formulation: Serves as a key solvent and carrier in the manufacture of pesticides, herbicides, and fungicides, enhancing the stability and efficacy of the final product.
• Polymer Industry: Employed as a solvent for polyimides, polyamides, and other high-performance polymers during synthesis and processing.
• Electrolyte Additive: Functions as a co-solvent in lithium-ion battery electrolytes to improve conductivity and battery performance at extreme temperatures.
• Chemical Intermediate: Acts as a precursor or building block in the synthesis of various specialty chemicals, including dyes, pigments, and photographic chemicals.
• Gas Purification: Utilized as an absorbent for acid gases like carbon dioxide and hydrogen sulfide in natural gas treatment and other industrial gas streams.
