Bacteriostatic Water is sterile, non-pyrogenic water containing 0.9% (9 mg/mL) benzyl alcohol as a bacteriostatic agent. It is not a peptide or an active compound; it functions as a laboratory diluent and reconstitution solvent for lyophilized research peptides and other freeze-dried reagents. The benzyl alcohol component distinguishes it from single-use sterile water by limiting microbial proliferation in solutions that are accessed more than once in a research setting. Supplied in sealed vials for laboratory use, Bacteriostatic Water is characterized for sterility and consistency so that reconstituted research materials can be prepared under controlled conditions. It is provided exclusively as a laboratory consumable for qualified research personnel. Not for human or animal use. Research laboratory use only.
All compounds referenced are supplied for laboratory and research applications only and are not for human consumption.
Bacteriostatic Water consists of sterile water combined with benzyl alcohol at a nominal 0.9% concentration, which serves as the bacteriostatic (antimicrobial-preservative) component. Benzyl alcohol is among the antimicrobial preservatives long characterized for use in parenteral and multiple-withdrawal formulations, where its inclusion limits microbial growth in solutions accessed more than once.1 In the reconstitution of lyophilized proteins and peptides, the diluent and its excipients are a recognized variable in laboratory technique; benzyl alcohol has specifically been studied for its interaction with reconstituted lyophilized protein formulations, including its effect on the physical state of the dissolved protein.2 These reports frame Bacteriostatic Water’s role generically as a reconstitution solvent used to return freeze-dried research materials to solution, rather than as an active compound with a biological target of its own. In a research setting it is handled as a laboratory consumable — stored, withdrawn, and combined with lyophilized reagents under aseptic technique appropriate to the receiving material. The citations below are technique-oriented: they address benzyl alcohol as a bacteriostatic agent and the reconstitution of lyophilized formulations, and are provided to document standard laboratory-handling context rather than to support any claim about Bacteriostatic Water as an active or investigational compound.
