53994-69-7 - Reference Information
| overview | 7-amino -3-chloro -3-cephalocyclic -4-carboxylic acid (abbreviated as 7-ACCA),7-ACCA is the key intermediate for the synthesis of the second-generation cephalosporin cefaclor. my country successfully developed cefaclor raw materials in the 2090 s, but the synthesis of raw materials has not yet achieved large-scale industrialization. The domestic production of cefaclor preparations mainly relies on imported foreign raw materials for repackaging. The main reason is 7-ACCA The synthesis process is not yet mature. |
| biological activity | 7-Amino-3-chloro cephalosporanic acid (7-ACCA) is an important intermediate for the synthesis of the second generation cephalosporin cefaclor Cefaclor (HY-B0198). |
| use | as an intermediate for cephalosporins |
