Description

Hbed CAS NO 35998-29-9 is a high-purity chelating agent and chemical intermediate, specifically N,N'-Bis(2-hydroxybenzyl)ethylenediamine-N,N'-diacetic acid. This compound is valued for its strong metal-chelating properties, making it essential for applications requiring precise control of metal ions. It is primarily needed by manufacturers in the pharmaceutical, water treatment, and specialty chemical synthesis industries for research, development, and production processes.

Application

• Pharmaceutical Synthesis: Used as a key intermediate or chelating agent in the production of active pharmaceutical ingredients (APIs) and diagnostic agents.
• Water Treatment Formulations: Acts as a scale and corrosion inhibitor in industrial water systems by sequestering problematic metal ions like calcium and iron.
• Chemical Research & Development: Serves as a versatile ligand in coordination chemistry for catalyst development and metal complex studies.
• Analytical Chemistry: Employed in the preparation of buffer solutions and as a masking agent in complexometric titrations and trace metal analysis.
• Agrochemicals: Incorporated into certain pesticide and fertilizer formulations to improve stability and bioavailability.
• Personal Care Products: Used in select cosmetic and personal care formulations as a stabilizer for products sensitive to metal-catalyzed degradation.

Quality Control

Our Hbed is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for industrial and research applications. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
