Reconstitution water

Bacteriostatic water for injection is sterile water that contains 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits microbial growth, allowing the solution to be used for multiple reconstitutions over a period of time — unlike sterile water for injection, which must be used immediately after opening and cannot be stored. The benzyl alcohol preservative works by disrupting bacterial cell membranes through its amphipathic structure, which inserts into and disorganizes the lipid bilayer. At the 0.9% concentration used in bacteriostatic water, it is bacteriostatic (inhibits growth) rather than bactericidal (kills). This level is sufficient to prevent microbial contamination during the multi-use period while being well-tolerated in research applications. Bacteriostatic water is the standard diluent for reconstituting lyophilized peptides in research settings. When added to lyophilized peptide vials, it dissolves the peptide while the benzyl alcohol preservative maintains sterility for the use period. The water is isotonic-compatible and has a neutral pH, making it suitable for peptide reconstitution without affecting peptide stability or activity.

Used as a diluent, not a therapeutic agent. Typical reconstitution volumes are 1-3 mL per peptide vial, adjusted to achieve desired concentration.

Store at 2-8°C (refrigerated). Keep away from direct light. Do not freeze unless specified. Check the Certificate of Analysis for batch-specific storage recommendations and expiration dating.
