Description

2-Amino-2-(4-Chlorophenyl)Ethanesulfonic Acid is a specialized organic sulfonic acid derivative that serves as a critical building block in advanced chemical synthesis. Its unique structure, featuring both an amino group and a sulfonic acid moiety on a chlorophenyl-substituted ethane backbone, makes it a valuable intermediate for creating compounds with tailored biological or physicochemical properties. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to develop new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key starting material for the synthesis of novel drug candidates, particularly in the development of enzyme inhibitors or receptor modulators.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, or plant growth regulators that require a chlorophenyl sulfonate scaffold.
• Biochemical Research: Serves as a precursor or a buffer component in specialized biochemical assays and protein studies due to its zwitterionic potential.
• Material Science: Employed in the synthesis of functional polymers, surfactants, or liquid crystals where the introduction of a sulfonic acid group is required for solubility or ionic character.
• Chemical Reference Standard: Supplied as a high-purity standard for analytical testing, method development, and quality control in chemical manufacturing.
