Product Overview
Heptanesulfonic acid sodium salt is a high-purity ion-pairing reagent specifically designed for HPLC applications. This compound is widely used as a mobile phase modifier to improve the separation of ionic and polar compounds in reversed-phase chromatography. Its long hydrophobic alkyl chain enhances retention and selectivity for analytes with varying polarities, ensuring sharp, well-resolved peaks. The sodium salt form provides excellent solubility in aqueous and organic solvents, making it compatible with a broad range of HPLC methods. With minimal UV absorbance, it does not interfere with detection at common wavelengths, ensuring accurate and reliable results. The reagent is rigorously tested for purity, residual solvents, and heavy metals, meeting strict HPLC-grade standards. Its stability under typical chromatographic conditions ensures consistent performance across multiple runs, reducing variability in analytical workflows. Whether used for small-molecule analysis or complex mixtures, this reagent delivers reproducible retention times and peak shapes, making it a trusted choice for demanding separations.
FAQs
1. What is the primary application of heptanesulfonic acid sodium salt in HPLC?
It is primarily used as an ion-pairing reagent in reversed-phase HPLC to improve the separation of ionic or polar compounds by modifying their retention behavior.
2. Is this reagent compatible with mass spectrometry (LC-MS) applications?
While it can be used, its non-volatile nature may cause ion suppression or source contamination in LC-MS. Volatile ion-pairing reagents are generally preferred for MS compatibility.
3. How should this product be stored for long-term stability?
Store in a tightly sealed container at room temperature, protected from moisture and light. Avoid exposure to extreme temperatures or humidity to prevent degradation.
4. What alternatives exist for ion-pair chromatography if this reagent is unavailable?
Alternatives include octanesulfonic acid sodium salt, pentanesulfonic acid sodium salt, or tetrabutylammonium salts, depending on the required selectivity and retention characteristics.
5. Does this reagent require any special handling precautions?
Handle with standard laboratory safety measures, including gloves and eye protection. Avoid inhalation or direct contact, and work in a well-ventilated area or fume hood.
