Penicillin V Potassium Salt (CAS 132-98-9) is the potassium derivative of phenoxymethylpenicillin, a beta-lactam antibiotic that appears as a white or off-white crystalline powder and is used in oral antibiotic therapies, veterinary formulations and culture media. It targets penicillin-binding proteins to inhibit bacterial cell wall synthesis, effective against streptococci and staphylococci in therapeutic dosages.

Penicillin V Potassium Salt
Applications
Deployed in oral antibiotic therapies for respiratory infections; in veterinary formulations for livestock prophylaxis; in culture media for microbial selection; in diagnostic kits for allergy testing; and in bulk pharma manufacturing for compounded preparations serving remote healthcare facilities.
Safety & Risks
High risk of hypersensitivity reactions, including severe anaphylaxis; contraindicated for those with beta-lactam allergies. Biohazard classification requires controlled environments; avoid aerosol formation during processing to prevent inhalation; dispose via incineration following pharmaceutical waste protocols to mitigate environmental antibiotic resistance.
Packaging
Enclosed in 15 kg sterile aluminum composite canisters with vacuum seals for sterility maintenance. Refrigerate in dedicated pharma-grade coolers, monitored for temperature excursions during transit.
