| Use | Iodine seronin (triiodothyronine) intermediate. |
| Production method | Tyrosine is iodized with iodine chloride and hydrochloric acid to generate 3,5-diiodotyrosine, and then acylated with acetic anhydride to obtain 3,5-diiodo-N-acetyltyrosine, which is esterified with ethanol under the action of p-toluenesulfonic acid to prepare the product. |
