应用
Tetraethyl Orthocarbonate is used in the synthesis of chemokine receptor-5 inhibitors against HIV-1, benzobisoxazoles and in the preparation of organic semiconductors. It is also employed in the synthesis of 2,7-dimethylene-1,4,6,9-tetraoxaspiro[4,4]nonane and in the synthesis of cross linked poly(orthocarbonate)s used as organic solvent absorbent.

备注
Moisture Sensitive. Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Keep away from ignition sources. Store under inert atmosphere and refrigerated.
