Overview

Oxiran-2-ylmethanol (CAS 556-52-5) is an epoxide compound with highly reactive three-membered ring structure and significant industrial applications. This glycidyl alcohol derivative, also known by its IUPAC designation oxiran-2-ylmethanol, represents a critical intermediate in epoxy chemistry and polymer synthesis. With the molecular formula C3H6O2 and molecular weight of 74.08 g/mol, this compound features both an epoxide ring and a hydroxyl group, making it exceptionally versatile for chemical modifications and cross-linking reactions. The substance exhibits significant hazard characteristics, classified under multiple danger categories including carcinogenicity (1B), mutagenicity (2), and reproductive toxicity (1B), requiring stringent handling protocols and appropriate safety equipment. Its acute toxicity properties and skin irritation potential necessitate comprehensive risk management procedures in industrial applications. The compound falls under ADR transport class 6.1, reflecting its toxic nature during shipping and storage. Primary industrial applications include epoxy resin production, where oxiran-2-ylmethanol serves as a reactive diluent and cross-linking agent. The pharmaceutical and agrochemical industries utilize this compound as a building block for synthesizing complex molecules. Additionally, it functions as an intermediate in specialty polymer manufacturing, particularly in applications requiring enhanced adhesion properties. Unlike related compounds such as chloromethylbenzene or N-methylaniline, which serve different synthetic pathways, oxiran-2-ylmethanol's dual functionality as both epoxide and alcohol makes it particularly valuable for creating branched polymer structures and surface modification applications. OYSI provides technical-grade oxiran-2-ylmethanol with comprehensive documentation and regulatory compliance support for European industrial customers.

Frequently Asked Questions

What is oxiran-2-ylmethanol?

Oxiran-2-ylmethanol is a chemical compound with the molecular formula C3H6O2 and CAS number 556-52-5. This substance has a molecular weight of 74.08 g/mol and belongs to the epoxy alcohol family. It is classified as a highly hazardous substance with multiple health risks including carcinogenic, mutagenic, and reproductive toxicity properties. The compound requires careful handling due to its acute toxicity and skin irritation potential, warranting strict safety protocols in industrial applications.

What are the physicochemical properties of oxiran-2-ylmethanol?

Oxiran-2-ylmethanol is a liquid organic compound at room temperature with characteristic properties typical of epoxy alcohols. The substance contains both an epoxide ring and a hydroxyl group, making it reactive and polar. Due to its hydroxyl group, it exhibits good solubility in polar solvents and water. The compound's molecular structure with the epoxide functionality makes it highly reactive, particularly in ring-opening reactions, which contributes to its industrial utility but also to its hazardous nature.

What is oxiran-2-ylmethanol used for?

Oxiran-2-ylmethanol serves as an important intermediate in organic synthesis and industrial chemical processes. The compound is primarily used in the production of various chemical derivatives through its reactive epoxide and alcohol functional groups. It finds applications in polymer chemistry, pharmaceutical synthesis, and as a building block for specialty chemicals. Due to its high toxicity profile, its use is restricted to professional industrial settings with appropriate safety measures and regulatory compliance.

How to handle oxiran-2-ylmethanol safely?

Oxiran-2-ylmethanol requires extreme caution during handling due to its classification as Carc. 1B, Muta. 2, and Repr. 1B.
