The field of organic chemistry is constantly evolving, with a continuous search for versatile building blocks that can unlock new synthetic pathways and material properties. 1,2-Difluoroethane (CAS 624-72-6) has emerged as a compound of significant interest, offering unique fluorination capabilities that are highly valued across various industrial sectors. This article serves as a guide for chemists, researchers, and procurement professionals seeking to understand and source this important chemical intermediate.

Understanding 1,2-Difluoroethane: Properties and Characteristics

1,2-Difluoroethane, identified by CAS number 624-72-6, is a colorless gas with a molecular formula of C2H4F2. Its key physical properties include a boiling point of 31°C, a density of 0.913 g/cm³, and a refractive index of 1.254. It is commonly supplied with a minimum purity of 95%. The presence of two fluorine atoms attached to adjacent carbon atoms makes it a potent precursor for introducing specific fluorinated functional groups into more complex molecules. This strategic fluorination can impart desirable characteristics such as increased thermal stability, enhanced chemical resistance, altered electronic properties, and modified biological activity.

Industrial Applications: A Versatile Intermediate

The industrial utility of 1,2-Difluoroethane is broad, primarily stemming from its role as a chemical intermediate. Its applications include:
