Science-backed research overview for this compound
Bacteriostatic Water for Injection is sterile, non-pyrogenic water that contains 0.9% (9mg/mL) of benzyl alcohol added as a bacteriostatic preservative. This allows the vial to be used multiple times over a period of up to 28 days once opened.
The benzyl alcohol inhibits the growth of potentially contaminating bacteria that could be introduced during multiple needle entries. This is critical for maintaining the sterility of reconstituted peptides throughout the duration of a research protocol.
In laboratory settings, bacteriostatic water is the gold standard for reconstituting lyophilized peptides. It ensures that the fragile peptide bonds remain stable and that the solution remains sterile for subcutaneous or intramuscular administration in research models.
