Description

1-Heptanesulfonicacid CAS NO 149158-18-9 is a high-purity, strong organic acid sulfonate widely utilized as a key ion-pairing reagent in analytical chemistry. Its primary value lies in its ability to enhance the separation and detection of basic compounds, particularly in reversed-phase liquid chromatography (HPLC). This product is essential for analytical laboratories and manufacturers in the pharmaceutical, biotechnology, and chemical research sectors requiring precise and reliable chromatographic analysis.

Application

• As a mobile phase additive (ion-pairing agent) in High-Performance Liquid Chromatography (HPLC) for the analysis of basic drugs, peptides, and biomolecules.
• Critical reagent in the quality control and purity testing of active pharmaceutical ingredients (APIs) and finished drug products.
• Used in analytical method development and validation to improve peak shape, resolution, and reproducibility.
• Employed in the separation and purification of cationic compounds in research and development laboratories.
• Applicable in environmental analysis for detecting and quantifying basic organic pollutants.
• Potential use as a catalyst or intermediate in specialized organic synthesis processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after each use to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
