A kind of seven-membered heterocyclic compound or its salt, its preparation method and application |
| abstract |
The invention discloses a seven-membered heterocyclic compound or a salt thereof, a preparation method and application thereof. The present invention provides a seven-membered heterocyclic compound represented by formula 7a or a salt thereof. The present invention also provides the application of the seven-membered heterocyclic compound represented by formula 7a or its salt as an impurity standard of elaprime. By using the seven-membered heterocyclic compound shown in the formula 7a of the present invention as a reference substance, an analytical method for quality control of elapulin can be established, thereby improving the safety and effectiveness of clinical application of elapulin. |
