Dimethyl Oxalate, identified by its CAS number 553-90-2, is a chemical compound characterized by its white crystalline appearance and a molecular formula of C4H6O4. Its molecular weight is approximately 118.09 g/mol. Understanding its detailed properties is crucial for its effective and safe application in various industries, from pharmaceuticals to organic synthesis.
Key physical properties of Dimethyl Oxalate include a melting point range of 50-54°C, indicating it is a solid at room temperature. Its boiling point is around 163.5°C at atmospheric pressure. The density is typically around 1.2 g/cm³. In terms of solubility, it is soluble in ethanol and shows slight solubility in water, with a solubility of 60 g/L at 25°C. Its flash point is 75.0°C, marking it as a combustible material.
Chemically, Dimethyl Oxalate is considered stable under normal conditions but is incompatible with strong oxidizing agents, acids, bases, and reducing agents. This incompatibility necessitates careful storage and handling to prevent hazardous reactions. The compound's precise mass is 118.026611, and its topological polar surface area is 52.60000. Its LogP value of -0.34 suggests it is moderately hydrophobic.
Safety is a paramount concern when working with Dimethyl Oxalate. As a combustible solid, it should be kept away from ignition sources. In case of exposure, it can cause skin, eye, and respiratory tract irritation. High exposure levels can be harmful. Therefore, appropriate personal protective equipment (PPE), such as gloves, eye protection, and respiratory protection if handling powders, is essential. Storage recommendations include keeping containers tightly closed in a dry and well-ventilated place, preferably in a cool location. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. provide detailed Safety Data Sheets (SDS) that offer comprehensive information on handling, first aid measures, and spill response procedures.
When sourcing Dimethyl Oxalate, understanding these chemical and physical properties, along with the associated safety guidelines, is vital for procurement managers and chemists. Ensuring a high assay (≥99.0%) and low water content (≤0.10%) guarantees the quality needed for demanding applications. The price of Dimethyl Oxalate is often reflective of its purity and the scale of order, making it important to compare offerings from reliable suppliers.
