Benzylpenicillin Potassium (Penicillin G Potassium)
1. Product OverviewBenzylpenicillin Potassium, also known as Penicillin G Potassium, is a classic first-generation β-lactam antibiotic API. It is produced via microbial deep fermentation followed by crystallization and purification processes, presenting as white crystalline powder with strong broad-spectrum bactericidal activity against gram-positive bacteria and partial gram-negative pathogens. Our product complies with major international pharmacopoeia standards (USP, EP, BP, CP), manufactured in GMP-certified workshops, and serves as the core raw material for sterile injectable penicillin powder for global pharmaceutical manufacturers.

3. Pharmacological MechanismBenzylpenicillin Potassium exerts bactericidal effects by inhibiting the synthesis of bacterial cell walls. It blocks the cross-linking reaction of peptidoglycan, the key structural component of bacterial cell membranes, leading to incomplete cell wall formation, osmotic lysis and death of sensitive bacteria.It shows potent activity against Streptococcus, Staphylococcus, Pneumococcus, Neisseria gonorrhoeae, Clostridium tetani and other gram-positive pathogenic bacteria.
4. Main Application Fields- Human Pharmaceutical APIRaw material for sterile injectable Benzylpenicillin Potassium powder, clinically used for the treatment of respiratory tract infections, skin and soft tissue infections, septicemia, syphilis, tetanus and other bacterial infectious diseases.
- Veterinary Antibiotic Raw MaterialFor prevention and treatment of livestock and poultry bacterial infections in animal health preparations.
