Product Technical Details

Product Overview

Oxirane, universally recognized within the professional chemical industry as Ethylene Oxide, represents a fundamental organic compound characterized by its simple yet highly reactive cyclic ether structure. Registered under CAS number 75-21-8, this substance serves as a critical building block in modern organic synthesis and large-scale industrial manufacturing. The three-membered epoxide ring imparts significant ring strain to the molecule, making it exceptionally reactive towards nucleophiles. This unique chemical property enables its widespread utilization across various high-value sectors, ranging from agrochemical production to the manufacture of consumer care products and polymers. Our facility specializes in the supply of high-purity grades suitable for demanding synthetic applications where consistency is paramount.

The molecular formula C2H4O reflects its simple yet potent structure. As a colorless transparent liquid at controlled temperatures, it requires precise handling protocols due to its volatility and reactivity. We adhere to strict manufacturing standards to ensure consistency in every batch delivered to our global partners. Understanding the chemical behavior of this intermediate is essential for downstream processing, and we provide comprehensive technical support to ensure safe and effective integration into your production lines.

Industrial Applications

The versatility of Oxirane makes it an indispensable raw material in the chemical value chain. A primary application lies in the agrochemical sector, where it functions as a key intermediate in the synthesis of herbicides such as Pretilachlor. This role underscores its importance in supporting global agricultural productivity through effective weed management solutions. The high purity of our supplied material ensures optimal yields in these complex synthetic routes.

Beyond pesticides, this compound is extensively used as a precursor for ethylene glycol, which is vital for antifreeze formulations and polyester production. It is also employed in the manufacture of ethanolamine and various non-ionic surfactants. These surfactants find applications in synthetic detergents, emulsifiers, and paper sizing agents. Additionally, its properties allow for use as a sterilizing agent for medical equipment and a fumigant for stored products, although these uses require specialized regulatory compliance and safety measures. We also supply this material for the production of cellulolytic agents, diluents, and plasticizers.
