| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | used as acylating agent and alkylating agent in organic synthesis, can also be used for the determination of phosgene and organophosphorus pesticide analysis. The product is toxic and irritating. |
| production method | from the reaction of 4-benzylpyridine nitrate with concentrated sulfuric acid. The two materials were heated together to 50 °c, poured into ice after 5min, and neutralized with ammonia under cooling. It is then extracted with diethyl ether, and the extract is concentrated and crystallized to give the final product in a yield of more than 50%. |
