$14.99
Sterile bacteriostatic water for injection containing 0.9% benzyl alcohol as an antimicrobial preservative. BAC Water is commonly used as a multidose diluent in peptide and biologic research workflows where repeated vial access is required.
Compound Details
Mechanism of Action
Provides a sterile aqueous vehicle with benzyl alcohol-mediated bacteriostatic activity that suppresses growth of common microorganisms after vial puncture. Designed to preserve multidose vial integrity under aseptic handling conditions.
Molecular Profile
- Molecular Weight
- 18.02 Da (H2O) + 108.14 Da (benzyl alcohol excipient)
- Purity Spec
- Sterile, pyrogen-free water with 0.9% benzyl alcohol (USP multidose standard)
Storage
Store at controlled room temperature (20-25°C). Keep vial sealed and protected from light. After first puncture, maintain aseptic handling and discard per laboratory protocol (commonly 28 days).
