Research Context (Literature Review) BAC Water
Note: The following information is for educational purposes regarding the chemical properties of this solvent and does not constitute a medical claim.
Bacteriostatic water is a standard solvent used in the laboratory to reconstitute lyophilized (freeze-dried) compounds. The addition of 0.9% benzyl alcohol acts as a bacteriostatic agent, inhibiting the growth of most potentially contaminating bacteria in reusable containers.
In research applications, the pH of bacteriostatic water (average 5.7) is generally compatible with the stability profiles of most peptide structures, allowing for longer storage of reconstituted solutions at 2-8°C compared to sterile water alone. This is crucial for maintaining the integrity of peptide bonds during experimental use.
