Product Description

6-Aminopenicillanic Acid (CAS 551-16-6) is a core intermediate in the synthesis of a wide range of β-lactam antibiotics. It contains the essential penicillin nucleus, making it a vital raw material for producing semi-synthetic penicillins like amoxicillin, ampicillin, and others. Its role in pharmaceutical manufacturing is critical due to its ability to be chemically modified into different antibiotic derivatives.
