| 2,3-Naphthalenedicarboxylic Anhydride Usage And Synthesis |
| Appearance | 2,3-NAPHTHALENEDICARBOXYLIC ANHYDRIDE is a pale Beige Solid. | | Description | A few years ago, the product was still synthesized from the corresponding diacid, but in recent years, it has been difficult to find the shadow of the diacid in the market, and the sales of this product have been repeatedly restricted, resulting in high prices. | | Uses | 2,3-Naphthalic anhydride is used as a reagent to synthesize analogues of Thalidomide (T338850), an inhibitor of tumour necrosis factor that was once abandoned because it caused birth defects, but is currently used as an inhibitor of angiogenesis in patients with multiple myeloma. |
