Description

Hydrogen Phosphate Ionophore I CAS NO 32065-17-1 is a highly selective, neutral carrier molecule designed for the potentiometric detection of dihydrogen phosphate (H₂PO₄⁻) ions. This compound matters for its critical role in the fabrication of ion-selective electrodes (ISEs) and optical sensors, enabling precise and reliable measurement in complex matrices. It is primarily needed by manufacturers and R&D laboratories in the analytical instrumentation, environmental monitoring, and biomedical diagnostics sectors for developing advanced sensing solutions.

Application

• Key component in the polymeric membrane of dihydrogen phosphate ion-selective electrodes (ISEs).
• Development of optical chemical sensors (optodes) for phosphate determination.
• Research and quality control applications in fertilizer analysis and soil testing.
• Monitoring phosphate levels in environmental water samples (e.g., wastewater, rivers).
• Potential use in clinical analyzers for biological fluid analysis.
• Fundamental studies in supramolecular chemistry and host-guest interactions.
• Integration into lab-on-a-chip and microfluidic sensing devices.
• Calibration standard for sensor validation and method development.
