6-Aminopenicillanic acid Chemical Properties,Usage,Production

Chemical Properties

WHITE TO CREAM FINE POWDER

Uses

(+)-6-Aminopenicillanic Acid is the core structure in penicillins, obtained from the fermentation brew of the Penicillium mold. (+)-6-Aminopenicillanic Acid is used as the main starting block for the preparation of numerous semisynthetic penicillins.

Uses

6-Aminopenicillanic acid is the basic unit in penicillin?s, which is obtained from the fermentation brew of the Penicillium mold. It acts as a starting material for the preparation of many semisynthetic penicillins. Further, it serves as apharmaceutical intermediate. In addition to this, it is used in antibiotics research and experimental application.

Definition

ChEBI: A penicillanic acid compound having a (6R)-amino substituent. The active nucleus common to all penicillins, it may be substituted at the 6-amino position to form the semisynthetic penicillins, resulting in a variety of antibacterial and ph rmacologic characteristics.

General Description

Chemical structure: ?-lactam

Flammability and Explosibility

Non flammable

Safety Profile

Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits very toxic fumes of NOx and SOx.

Purification Methods

This acid crystallises from water. [Kleppe & Stroninger J Biol Chem 254 4856 1979,Beilstein 27 III/IV 2858.]
