Deng potassium salt and Deng sodium salt can be obtained by reaction. The latter is an important side for preparing semi-synthetic penicillin, amoxicillin (ie, amoxicillin) and cephalosporin antibiotics, cefadroxil, cefoperazone, etc. Chain compound. It can also produce amoxicillin cephalosporin, cefprozil, ceftriaxone, etc., because of its wide use and synthetic pharmaceutical products that can be injected and taken orally, the clinical efficacy is better than that of ampicillin.
