N,N-Dimethyl.1.2.ethanediamine(CAS NO:108-00-9)

Properties: A colorless, transparent liquid with an amine-like odor. Its molecular formula is C₄H₁₂N₂ and its molecular weight is 88.151. It belongs to the class of symmetric dimethylethylenediamine compounds. The density at atmospheric pressure is 0.803-0.819 g/cm3 (with slight variations among different sources). The boiling point is 105.5-119°C at atmospheric pressure, and the melting point is -70°C. The refractive index is approximately 1.4255-1.431 (at 20°C).

Uses: It is an important organic chemical intermediate, primarily used in the synthesis of 1-dimethylaminoethyl-5-mercaptotetrazole, an intermediate for cefotiam. This represents a key step in pharmaceutical research and development. As an organic chemical intermediate, it finds wide application in fine chemicals, chemical pharmaceuticals, and biomedicine, particularly demonstrating significant value in the synthesis of antibiotic drugs. Beyond its use in cefotiam synthesis, its molecular structural characteristics may be applied in other organic synthesis reactions, though specific applications should be determined based on experimental requirements.
