Description

Sodium 1-Heptanesulfonate is a high-purity, water-soluble anionic surfactant and ion-pairing reagent. This compound is valued for its consistent performance as a critical mobile phase modifier in reversed-phase high-performance liquid chromatography (HPLC). It is essential for industries requiring precise analytical separation and quantification of basic compounds, including pharmaceutical development, quality control laboratories, and academic research institutions.

Application

• HPLC Analysis: Primarily used as an ion-pairing reagent in the reversed-phase HPLC analysis of basic pharmaceuticals, amines, and other cationic compounds to improve peak shape and resolution.
• Pharmaceutical Manufacturing: Employed in process development and quality control (QC) for the purification and analysis of active pharmaceutical ingredients (APIs) and intermediates.
• Biochemical Research: Utilized in the separation and study of peptides, proteins, and nucleotides via liquid chromatography techniques.
• Chemical Synthesis: Acts as a phase-transfer catalyst or surfactant in certain organic synthesis reactions.
• Material Science: Can be used in the preparation of specialty surfactants and surface modification agents.
