Ampicillin EP Impurity B, also known as L-Ampicillin, is a specific stereoisomeric impurity of the broad-spectrum antibiotic ampicillin. It serves as a critical reference standard for pharmaceutical quality control to ensure stereochemical purity during synthesis. The molecular formula is C16H19N3O4S, with CAS No. 6938-87-2.
Store at -20°C in a dry, dark environment to prevent degradation. Handle with appropriate PPE to avoid skin contact or inhalation, as beta-lactam compounds may cause sensitization. Not intended for clinical therapeutic use due to potential reduced efficacy compared to the active enantiomer.
