Physical and Chemical Properties | Properties Glyoxal -1, 1-dimethylacetal has a boiling point of 63.9 ℃, a density of 0.99(1g/cm3) and a vapor pressure of 168(mmHgat25 ℃). |
Use | Application of glyoxal-1, 1-dimethylacetal is a colorless, low-toxic, non-volatile aldehyde, containing an aldehyde group with higher reactivity and an acetal group with lower reactivity but can be easily converted into an aldehyde group. In synthetic chemistry, it is often used in reactions such as ring closing, extending the parent chain structure and introducing aldehyde groups. As an important fine intermediate, it is widely used in the resin industry, perfume industry and pharmaceutical industry. |
