7-ACCA - 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
