Applications

1. Ion-Pair Reagent in HPLC

Sodium 1-octanesulfonate丨CAS 5324-84-5 is widely used in reversed-phase high-performance liquid chromatography (RP-HPLC) as an ion-pairing agent. It improves the retention and separation of polar or ionic compounds, particularly:

● Basic drugs

● Amines

● Peptides

● Alkaloids

Its use enhances the resolution of analytes that otherwise elute poorly or not at all on conventional C18 columns.

2. Pharmaceutical Analysis

In pharmaceutical laboratories, sodium 1-octanesulfonate is used for the quantitative and qualitative analysis of active pharmaceutical ingredients (APIs), including antibiotics and antihistamines, by forming ion pairs that enhance UV absorbance and improve chromatographic behavior.

3. Surface-Active Agent

It acts as a surfactant and wetting agent in various analytical and industrial applications, contributing to solubilization and stabilization of hydrophobic compounds in aqueous media.

4. Analytical Reagent

Used in research and development settings for method validation, especially in bioanalytical studies, including plasma drug level determinations.
