Dear UC Chemicals users,
Many of you have received warnings in the UC Chemicals system indicating that your isopropanol (also known as isopropyl alcohol) is a peroxide-forming chemical and has expired. Please be aware that EH&S does not consider isopropanol to be capable under normal handling and storage conditions of forming organic peroxides, and does not regulate it as such. While EH&S always recommends disposing of chemicals which you no longer need, you are not required to dispose of your isopropanol at this time.
