For businesses operating in the pharmaceutical, agrochemical, and specialty materials sectors, securing a consistent and high-quality supply of chemical intermediates is paramount. 1,2-Difluoroethane (CAS 624-72-6) is one such intermediate that offers significant potential due to its fluorinated nature. This guide is designed to help procurement professionals and R&D scientists understand how to effectively buy 1,2-difluoroethane from China, a leading global hub for chemical manufacturing.

Understanding 1,2-Difluoroethane: Properties for Application

1,2-Difluoroethane is characterized by its molecular formula C2H4F2 and a CAS registry number of 624-72-6. It exists as a colorless gas with a boiling point of 31°C. Key properties include a density of 0.913 g/cm³ and a refractive index of 1.254. Typically, it is supplied with a minimum purity of 95%. This specific arrangement of fluorine atoms makes it an excellent building block for synthesizing complex molecules where enhanced stability, unique reactivity, or altered electronic properties are desired. Its applications range from being a crucial component in the synthesis of pharmaceuticals and agrochemicals to its use in specialty materials.

Why Source 1,2-Difluoroethane from China?

China's chemical manufacturing sector offers several advantages for international buyers:

• Cost-Effectiveness: The 1,2-difluoroethane price in China is often highly competitive, allowing businesses to manage their raw material costs effectively.
• Scalability: Chinese manufacturers typically possess large production capacities, capable of fulfilling orders from small research quantities to large industrial volumes.
• Extensive Network: The sheer number of manufacturers and suppliers ensures a wide variety of options, from basic grades to highly specialized purities.
