Description

6-Guanidinohexanesulfonic Acid is a specialized organic compound featuring both a guanidino group and a sulfonic acid moiety, making it a valuable building block and intermediate in advanced chemical synthesis. Its unique bifunctional structure allows it to act as a versatile linker or modifier, particularly in the development of bioactive molecules and functional materials. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and specialty chemical sectors seeking to develop novel compounds with enhanced properties.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates, particularly those targeting enzyme inhibition or requiring cationic charge carriers.
• Bioconjugation Reagent: Used to modify peptides, proteins, or other biomolecules by introducing a permanent positive charge or sulfonate group for solubility and stability enhancement.
• Catalyst and Ligand Synthesis: Serves as a precursor for creating specialized ligands in coordination chemistry or organocatalysts due to its strong hydrogen-bonding donor and acceptor sites.
• Polymer Modification: Incorporated into polymer chains to impart ionic character, improve hydrophilicity, or create functional materials for membranes and coatings.
• Biochemical Research: Utilized in proteomics and enzymology studies as a tool compound or analog for arginine-containing substrates.
• Surface Functionalization: Applied to modify material surfaces (e.g., nanoparticles, chromatography media) to introduce specific ionic interactions for separation or sensing applications.

Quality Control

Our 6-Guanidinohexanesulfonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and handling properties. For long-term storage, consider using a desiccant.
