Acetic AcidSterile Laboratory Solution · Lot-Traced

Acetic acid is a specialty reconstitution solvent used for a small handful of research peptides (notably TB-500 / Thymosin β4) that don't dissolve cleanly in plain bacteriostatic water. The mild acidity helps break the peptide out of its folded state so it goes fully into solution.

ProSource Labs supplies Acetic Acid in the following available vial sizes for research purchase: 5mL. Product SKU references: AA-5mL.

• Specialty Solvent: For peptides that don't fully dissolve in bacteriostatic water
• TB-500 Standard: The most common reconstitution solvent for Thymosin β4 preparation
• Mild Acidity: Just acidic enough to help unfold and dissolve stubborn peptides
• Small Volumes: A little goes a long way — typical protocols use tiny amounts

Each vial is sealed under sterile conditions in the source manufacturer's cGMP facility (for pharmaceutical-grade solutions like Hospira Bacteriostatic Water) or in a validated laboratory environment for laboratory-grade reagents. Vials are visually inspected for particulate matter and seal integrity before release.

Storage: Store at room temperature (15–30°C), tightly capped.

Because Acetic Acid is a liquid, freezing is not appropriate — freeze-thaw cycles can compromise the vial's seal, alter the concentration through water-ice expansion damage, and (for preserved solutions) can affect preservative distribution. Store the sealed vial upright.

All laboratory handling should follow the receiving institution's standard operating procedures for sterile reagents. Once a vial's rubber septum has been punctured, the contents should be treated per the corresponding manufacturer's product monograph.

Because Acetic Acid is a liquid reagent rather than a synthetic peptide, HPLC purity testing is not the relevant analytical method. Quality documentation for this product covers the manufacturer's certificate of sterility, endotoxin testing, fill-volume verification, and (for preserved products) preservative concentration analysis.

For pharmaceutical-grade products supplied through ProSource Labs (such as Hospira Bacteriostatic Water for Injection), the underlying manufacturer's FDA-approved product monograph is the authoritative reference for composition, storage, and in-use timelines. Request the source documentation from customer support after purchase if required for your institution's incoming QA workflow.

Reconstitution solvent for research peptides that resist standard bacteriostatic water. Most commonly used for TB-500 preparation in research research protocols.

Acetic Acid vials ship in tamper-evident, moisture-resistant, cold-chain-friendly outer packaging from our Southern California distribution facility for fast US domestic delivery — typically 2-4 business days coast-to-coast, with expedited options available at checkout.

Every Acetic Acid shipment is discreet — the outer packaging carries no product-specific branding or direct reference to the compound name inside, protecting researcher privacy. Tracking numbers are emailed automatically. For institutional or high-volume orders, dedicated wholesale pricing is available through the wholesale portal.
