Product details
Glacial (concentrated, anhydrous) acetic acid is supplied as a process-auxiliary solvent for labs that prepare acidic-pH reconstitution diluents in-house at custom concentrations. While the pre-prepared 0.6% Acetic Acid Water covers the most common acidic-pH case, some workflows need other concentrations (for example 0.1%, 0.3%, or 1.0%) depending on a specific peptide's solubility and stability behaviour; glacial acetic acid (≥ 99.7%) is the starting material from which those diluents are prepared at the target dilution. This SKU is a process auxiliary, not a peptide reference standard.
Peptuno supplies glacial acetic acid as a ≥ 99.0% solvent-grade reagent in sealed containers. Because it is a solvent rather than a peptide, the analytical scope is the standard solvent-grade specification — GC, water content, and residual-impurity profiling — rather than the peptide-style HPLC + mass-spec packet. A lab preparing in-house diluents should follow local pharmacopeia requirements for solvent quality, and any resulting diluent intended for injectable-grade research use must be sterilized after preparation. Standard chemical-safety handling applies (corrosive; use in a fume hood with appropriate PPE).
Regulatory note: Process-auxiliary solvent, not a peptide reference standard; supplied for Research Use Only. Corrosive — handle per standard chemical-safety practice. Diluents prepared in-house for injectable-grade research use must be sterilized after preparation, per the destination market's requirements.
FAQ
- Is glacial acetic acid the same as vinegar or dilute lab acetic acid?
- No. Glacial acetic acid is the anhydrous, concentrated (≥ 99%) form, distinct from food-grade vinegar (~4–7% in water) or dilute laboratory acetic acid (10–50% in water). 'Glacial' refers to the ice-like crystals pure acetic acid forms below its 16.6 °C freezing point. It is a solvent / process-auxiliary for preparing custom acidic-pH diluents — food-grade vinegar must not be substituted in research contexts, since the impurity profile is fundamentally different.
- How is glacial acetic acid characterized as a process auxiliary?
- As a solvent rather than a peptide, the analytical scope is the standard solvent-grade specification — GC for purity, water content, and residual-impurity profiling — not the peptide-style HPLC + mass-spec packet. A lab preparing diluents from it should follow local pharmacopeia requirements for solvent quality.
- What handling and downstream-sterility considerations apply?
- Glacial acetic acid is corrosive and its vapour is irritating, so handle it in a fume hood with chemical-resistant gloves and splash protection, stored in compatible containers away from strong oxidizers and bases. Any acidic-pH diluent prepared from it for injectable-grade research use must be sterilized after preparation; the supplied solvent itself is a process auxiliary, not a ready injectable diluent.
