Product Overview
1-Pentanesulfonic acid sodium salt monohydrate is a high-purity ion-pairing reagent specifically designed for HPLC and ion chromatography applications. This HPLC-grade chemical ensures minimal UV absorbance, making it ideal for sensitive analytical techniques where baseline stability is critical. Its monohydrate form guarantees consistent performance, while the sodium salt structure enhances solubility in aqueous and organic solvents. The compound’s hydrophobic alkyl chain (C5) provides optimal retention for polar and ionic analytes, improving peak resolution without column degradation. Rigorously tested for low heavy metal and impurity content, this reagent meets stringent lab standards for reproducibility. The 25 g pack size offers convenience for frequent use while maintaining cost efficiency. Store in a cool, dry place to preserve stability, and handle with standard lab precautions to avoid moisture absorption. Compatible with most reversed-phase and ion-exchange columns, it eliminates the need for alternative ion-pairing agents with inferior purity profiles.
FAQs
1. What is the shelf life of this HPLC-grade 1-pentanesulfonic acid sodium salt?
When stored in a tightly sealed container at room temperature (15–25°C), the product retains its stability for up to 24 months from the date of manufacture. Avoid exposure to humidity to prevent hydration changes.
2. Can this reagent be used with mass spectrometry (LC-MS) applications?
Yes, the high purity and low UV absorbance make it suitable for LC-MS, though volatility and ionization efficiency should be evaluated for specific analytes. Always optimize mobile phase conditions for compatibility.
3. What alternatives exist if this product is unavailable?
Heptanesulfonic acid sodium salt or octanesulfonic acid sodium salt can serve as alternatives, though retention times may vary due to differences in alkyl chain length. Adjust gradient conditions accordingly.
4. How should this chemical be disposed of after use?
Follow local regulations for hazardous chemical disposal. Neutralize with a dilute base (e.g., sodium bicarbonate) before disposal, and avoid releasing it into drains or the environment.
5. Is this product compatible with gradient HPLC methods?
Yes, it is fully compatible with gradient elution, but ensure the mobile phase pH and organic modifier concentration are optimized to prevent precipitation or column fouling.
