Description
Chemical Identity
Bacteriostatic Water analytical reference compound.
Research Overview
Bacteriostatic Water is sterile water preserved with 0.9% benzyl alcohol (9 mg/mL) as a bacteriostatic agent. It is a standard laboratory diluent used for reconstituting lyophilized research compounds. The benzyl alcohol preservative inhibits microbial growth, allowing for multiple aseptic withdrawals from a single container while maintaining sterility throughout the product’s use period.
Unlike sterile water for injection (which contains no preservative and is intended for single use), Bacteriostatic Water’s benzyl alcohol content provides ongoing antimicrobial protection. This makes it suitable for multi-use research applications where a single vial may be accessed multiple times over days or weeks. The 0.9% concentration is the standard USP specification for bacteriostatic preservative in aqueous diluents.
