Description

Carbonate Ionophore Iii is a highly selective neutral carrier used in the fabrication of ion-selective electrodes (ISEs) and optical sensors. Its core value lies in enabling precise and reliable detection of carbonate and bicarbonate ions in complex aqueous and biological matrices. This analytical reagent is essential for researchers and quality control laboratories in environmental monitoring, clinical diagnostics, and pharmaceutical development. The compound is supplied with full traceability under CAS No. 129476-45-5.

Application

• Primary component in carbonate ion-selective electrodes (ISEs) for direct potentiometric measurement.
• Development of optical chemical sensors (optodes) for carbonate detection in biological fluids.
• Environmental analysis of carbonate levels in natural waters, seawater, and soil extracts.
• Clinical diagnostic devices for monitoring blood bicarbonate/carbon dioxide levels.
• Process analytical technology (PAT) for in-line monitoring in biotechnology and fermentation processes.
• Research into cellular metabolism and respiration studies involving dissolved CO₂.
• Quality control in beverage and pharmaceutical industries where carbonate concentration is critical.

Quality Control

Every batch of Carbonate Ionophore Iii is manufactured and tested under strict quality management protocols to ensure consistent high performance in sensor applications. Our products undergo rigorous quality testing, including identity confirmation by spectroscopic methods and purity assessment by HPLC, to ensure compliance with industry standards for high-purity research chemicals. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
