Acetic Acid Solution

Not a research compoundSolubilisation aid

Also published as Dilute acetic acid, 0.6% acetic acid

A dilute acid solution used to bring hydrophobic or poorly water soluble peptides into solution when neutral water will not do it. It is a laboratory reagent, not a diluent for general use.

Where it came from

Standard laboratory practice in peptide chemistry.

Relevant background

  • Peptide solubility as a function of pH and isoelectric point
  • Acidic solubilisation of hydrophobic sequences

State of the evidence

Furthest it has gotNot a research compound

A reagent, not a study subject.

What a buyer should know

Peptides are least soluble near their isoelectric point, which is why acid helps for basic sequences and hurts for acidic ones. Using it by default rather than by solubility profile can precipitate material rather than dissolve it.

Handling and stability

Corrosive at concentration. Follow the safety data sheet for the grade supplied. Dilute solutions still warrant eye protection.
