About this compound
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is used in laboratory settings as a diluent for reconstituting lyophilized peptide reference materials, where the preservative limits microbial growth across repeated vial entries.
