Use
7-aminocephalosporanic acid is used in pharmaceutical intermediates. It is the starting material of many semi-synthetic cephalosporin. A variety of semi-synthetic cephalosporin industrial production is through fermentation to obtain cephalosporin C. Then obtain nucleus 7-ACA through chemical cleavage , and then the preparation is fininshed in chemically modified way .
