General description

Sodium 1-heptanesulfonate belongs to the sodium alkylsulfonate group of surfactants. It has a -SO?3 head group with sodium and an alkyl chain attached to the head group. Sodium 1-heptanesulfonate has a critical micelle concentration value of 0.302 mol/dm3.
Sodium 1-heptanesulfonate, also known as sodium heptanesulfonate, is a versatile compound commonly used in lab experiments and biochemical research. It acts as an ion-pairing agent, surfactant, and buffer, playing a crucial role in various applications. In biochemistry, it helps with tasks like protein purification and nucleic acid separation by reducing surface tension for better mixing. It also serves as a chelating agent for metal ion analysis and acts as a buffer in biological experiments. Sodium 1-heptanesulfonate is a preferred choice in HPLC and high-performance capillary electrophoresis analyses, aiding in the separation of positively charged analytes in both organic and inorganic compounds, from pharmaceuticals to peptide research.

Application

Sodium 1-heptanesulfonate has been used as a component of the mobile phase buffer for preequilibration of high performance liquid chromatography column.
Ion-pairing reagent for HPLC, including analyses of peptides and proteins.

Biochem/physiol Actions

Sodium 1-heptanesulfonate serves as an ion-pairing reagent for analysis of epinephrine and norepinephrine in ion-pairing chromatography (IPC).

Features and Benefits

  • Ideal for Cell Biology and Biochemical Research
