0.6% Acetic Acid Water

Some peptides dissolve poorly at neutral pH. A dilute acetic acid solution (pH 2.7–3.1) is the standard alternative diluent; we fill it in the same vial sizes and release it to the same document set.

Questions buyers ask

Is acetic acid water a replacement for bacteriostatic water?
No — it is a different diluent for compounds that need low pH. Most peptides use bacteriostatic water.
