Description

Sodium 1-Hexanesulfonate Monohydrate is a high-purity sulfonate salt widely used as a critical ion-pairing reagent in analytical chemistry. Its primary value lies in its ability to enhance the separation and detection of hydrophobic analytes in reversed-phase liquid chromatography. This product is essential for R&D and QC laboratories in the pharmaceutical, biotechnology, and chemical analysis sectors requiring precise and reproducible analytical results.

Application

• Ion-Pairing Reagent for HPLC: A key mobile phase additive for the separation of basic compounds, peptides, and pharmaceuticals in reversed-phase chromatography.
• Pharmaceutical Analysis: Used in the assay and impurity profiling of active pharmaceutical ingredients (APIs) to meet pharmacopeial standards (e.g., USP, EP).
• Biomolecule Separation: Facilitates the analysis of oligonucleotides, proteins, and other complex biomolecules in research and quality control.
• Chemical Intermediate: Serves as a building block or surfactant precursor in specialty chemical synthesis.
• Capillary Electrophoresis (CE): Employed as a background electrolyte modifier for improving separation efficiency.
• Reference Standard: Acts as a high-purity standard for method development and calibration in analytical laboratories.
