0.6% acetic-acid reconstitution diluent
Supply and ordering
Ask sales about Acetic Acid Water availability, order quantities, packaging, and batch documentation. Include other catalog items in the same inquiry if you are planning a combined or recurring order.
Overview
0.6% Acetic Acid in Water is a sterile acidic-pH reconstitution diluent specifically prepared for peptides that require acidic conditions for solubilization and stability. The 0.6% acetic acid concentration produces a solution at approximately pH 3.0-3.5, which is the operational range for many peptides that aggregate or precipitate at neutral pH. The most common application is reconstitution of recombinant growth factors like IGF-1 LR3 (which requires acidic-pH solubilization to maintain monomer form and prevent aggregation) and other cationic-or-amphipathic peptides where neutral-pH water produces precipitation or aggregate formation. PeptideXpo supplies 0.6% Acetic Acid Water in sterile 3 ml and 10 ml presentations, prepared from pharmaceutical-grade acetic acid and Water for Injection. Buyers should verify the sterility, bacterial endotoxin (LAL), and injectable-grade packaging requirements of the target destination market, different jurisdictions have somewhat different specifications for injectable-grade diluents, and the same product may be appropriate for some markets and not others depending on local pharmacopeia requirements.
Who buys this, and why
Custom-blend buyers are almost always OEM clients building a branded product around a specific ratio of two or more peptides. The development workflow is collaborative: ratio target, analytical method to verify it, stability protocol in the chosen carrier, and packaging selection are all defined in the OEM brief before the first commercial run. Sample-stage volumes are usually 5-10 g of finished blend; commercial MOQ depends on the components.
Primary buyer fit: 503A / 503B compounding pharmacies, academic and contract research laboratories, and regional distributors and re-sellers.

Frequently asked questions
Acidic-pH reconstitution diluent is required for peptides that aggregate, precipitate, or denature at neutral pH. The most common examples in our catalog are IGF-1 LR3 and unmodified MGF (both proteins that aggregate at neutral pH and need acidic conditions for monomer solubilization), and certain cationic / amphipathic short peptides that show better solubility at low pH. Most synthetic peptides (Tirzepatide, Semaglutide, BPC-157, TB-500, CJC-1295, Ipamorelin, and the cosmetic-peptide family) reconstitute cleanly in standard saline or bacteriostatic water, the acidic-pH diluent is the exception rather than the rule. Buyers should check the specific peptide's recommended diluent on the COA or the product page before defaulting to 0.6% Acetic Acid Water.
The 0.6% concentration produces a final pH around 3.0-3.5 in the reconstituted solution, which is the operational range for solubilizing IGF-1 LR3 and similar proteins that aggregate at neutral pH but denature at strongly acidic pH (below 2.5). Stronger acidic conditions (1% or higher acetic acid, pH below 2.5) can disrupt the protein's tertiary structure and produce biologically inactive material. Weaker acidic conditions (0.1% acetic acid, pH 4-5) don't provide enough protonation of the protein's residues to keep it in monomer form. The 0.6% concentration is the well-established compromise, strong enough to maintain monomer solubility, gentle enough to preserve native structure for the protein's intended biological activity once diluted into physiological conditions.
The catalog item is the ready-to-use 0.6% dilution in 3 ml and 10 ml presentations; this is the acidic-pH diluent the vast majority of buyers need, and it removes the handling burden of a corrosive concentrate. Buyers whose workflow genuinely requires a different acetic-acid concentration (0.1%, 0.3%, 1.0%) should raise it at quote stage so the requirement can be handled through the OEM service rather than by preparing dilutions from a concentrate on site. Whatever the concentration, the resulting diluent must meet the sterility and endotoxin requirements of the destination market before any injectable-grade use.
Send any vial from your order to an independent laboratory of your choice. If the report shows the product does not meet the specification on its COA — purity below the stated minimum, or an identity that does not match — share the report with our sales team and we refund that product in full.
