Description

Bisulfite Ionophore CAS NO 497151-94-7 is a specialized organic compound designed for the selective recognition and binding of bisulfite (HSO₃⁻) ions. This compound is critical for the development of highly sensitive and selective chemical sensors and analytical detection systems. It is primarily utilized by researchers and manufacturers in the fields of analytical chemistry, environmental monitoring, and industrial process control.

Application

• Bisulfite Ion-Selective Electrodes (ISEs): Core component in the fabrication of potentiometric sensors for the direct measurement of bisulfite concentration in aqueous solutions.
• Optical Chemical Sensors: Used as a recognition element in fluorescent or colorimetric sensor systems for the visual or instrumental detection of sulfite/bisulfite.
• Food and Beverage Quality Control: Enables precise monitoring of sulfite levels, which are used as preservatives in wines, dried fruits, and other food products.
• Environmental Analysis: Detection and quantification of sulfur dioxide (SO₂) derivatives in air and water samples for pollution control and regulatory compliance.
• Pharmaceutical Analysis: Assay development for determining sulfite antioxidants in certain drug formulations.
• Industrial Process Monitoring: Real-time analysis of bisulfite in scrubber solutions and other chemical processes in the pulp/paper and petrochemical industries.
