What are some of the preservatives used in the most common ethers and chlorinated solvents and why are they added?
• Certain solvents will degrade over time requiring special handling and storage considerations. In addition, the products of certain degradation processes pose a potential safety risk if present at sufficiently high levels. For these types of materials, small amounts of stabilizing chemicals are added to slow down or stop material degradation. It is important to understand the stability of materials in use and if unclear, consult the Sigma-Aldrich Technical Support and MSDS Centers.
