BAC WATER (BACTERIOSTATIC WATER)

Bacteriostatic Water for Injection USP is a sterile preparation of water containing 0.9% (9mg/mL) benzyl alcohol as a bacteriostatic preservative. It is a standard pharmaceutical-grade research laboratory solvent supplied for the reconstitution of lyophilized research compounds.
Research Laboratory Applications
In research laboratory settings, bacteriostatic water serves as a preferred reconstitution vehicle for lyophilized peptide compounds due to its multi-dose utility. The benzyl alcohol preservative allows prepared solutions to be accessed multiple times from a single vial while maintaining sterility between uses.
Benzyl Alcohol Preservative Chemistry
Benzyl alcohol functions as an antimicrobial preservative through disruption of bacterial cell membrane integrity and interference with cellular metabolic processes in aqueous solution formulations.
