Bacteriostatic Water
0.9% benzyl alcohol in sterile water
Sterile water containing 0.9% benzyl alcohol as a bacteriostatic agent, used as a diluent for reconstituting lyophilised peptides.
What ships with each compound
Each vial is filled from a single synthesis batch and carries that batch number on the label. The matching Certificate of Analysis records the purity determined by HPLC, the identity confirmed by mass spectrometry, and the date the analysis was performed — so the document can be tied to the specific material in front of you rather than to a product line in general.
Select batches are additionally sent to an independent third-party laboratory for purity verification. We do not claim that every batch receives independent verification, because it does not, and the unqualified version of that claim also misattributes our own in-house chromatography to somebody else's laboratory.
Bacteriostatic water is a solvent, not an assayed peptide, and carries no purity specification — any vendor quoting a purity percentage for it is quoting a number that does not exist. How to read a Certificate of Analysis walks through the document field by field.
