Description

3-(Hexadecylamino)-1-Propanesulfonic Acid is a high-purity, amphoteric surfactant and biochemical reagent. This compound is valued for its unique combination of a long hydrophobic alkyl chain and a hydrophilic sulfonic acid group, making it an effective zwitterionic buffer and detergent. It is primarily utilized by researchers and manufacturers in the life sciences, pharmaceutical development, and specialty chemical synthesis sectors for applications requiring precise pH control and mild solubilization.

Application

• As a key component in zwitterionic buffer systems for biochemical and molecular biology research.
• Utilized in the formulation of mild, non-denaturing detergents for membrane protein isolation and stabilization.
• Employed as a specialty surfactant in the development of personal care products and high-performance cleaning formulations.
• Serves as an intermediate in the organic synthesis of more complex amphoteric compounds and pharmaceutical agents.
• Used in diagnostic reagent formulations where consistent pH and low interference are critical.
• Applied in chromatography and electrophoresis as a buffer additive to improve separation and recovery.
