Sterile 0.6% acetic acid solution is a specialized peptide reconstitution solvent used for peptides with high isoelectric points that may not dissolve readily in neutral pH bacteriostatic water. The acidic pH (~3.0) protonates basic residues and improves solubility for peptides such as IGF-1 LR3 and other basic or hydrophobic research compounds.
Biochemical Characteristics
Specifications
Molecular Formula
CH3COOH (diluted)
CAS Number
64-19-7
0.6% acetic acid in sterile water provides a pH of approximately 3.0. At this pH, basic amino acid residues (Arg, Lys, His) are fully protonated, increasing the net positive charge of basic peptides and enhancing their aqueous solubility.
This is the standard reconstitution solvent for peptides with isoelectric points above 7.0 that show poor solubility in neutral water.
Tested for sterility, acetic acid concentration, pH, and endotoxin.

Frequently Asked Questions
Acetic Acid 0.6% is verified at ≥99.9% purity via reverse-phase HPLC analysis. Each batch also undergoes ESI mass spectrometry for identity confirmation, LAL endotoxin testing (<0.1 EU/mg), and USP <71> sterility testing. A batch-specific Certificate of Analysis (COA) is included with every order.
Lyophilized (powder): Store at -20°C, protected from light and moisture. Shelf life: 24 months. Reconstituted (solution): Store at 2-8°C, use within 30 days. Critical: Allow the vial to reach room temperature before opening to prevent moisture condensation inside the vial. Avoid repeated freeze-thaw cycles (max 3 recommended).
The CAS registry number for Acetic Acid 0.6% is 64-19-7. Molecular formula: CH3COOH (diluted). Full chemical characterization data including PubChem identifiers, SMILES notation, and InChIKey are available on the Chemical Properties tab above.
Yes. Every batch of Acetic Acid 0.6% is independently tested by Janssen Analytical Laboratories (ISO 17025-accredited). Testing includes HPLC purity analysis, mass spectrometry identity confirmation, LAL kinetic turbidimetric endotoxin assay, and USP <71> sterility testing. Full results are provided in the batch-specific COA. Additional documentation is available on the COA/HPLC/MS and 3rd Party Testing tabs above.
