Description

Cdta CAS NO 482-54-2 is a high-purity chelating agent, specifically the tetrasodium salt of trans-1,2-diaminocyclohexane-N,N,N',N'-tetraacetic acid. This compound is valued for its exceptional ability to form stable complexes with a wide range of metal ions, particularly calcium and heavy metals, under demanding conditions. It is an essential reagent for industries requiring precise metal ion control, such as pharmaceutical manufacturing, analytical chemistry, and detergent formulation.

Application

• Pharmaceutical Synthesis & Formulation: Acts as a stabilizing agent and metal chelator in injectable solutions and topical preparations to prevent catalytic degradation.
• Analytical Chemistry: Used as a masking agent in complexometric titrations (e.g., water hardness testing) and to prepare buffer solutions for trace metal analysis.
• Industrial Cleaning & Detergents: Enhances the performance of cleaning formulations by sequestering calcium and magnesium ions that cause water hardness.
• Pulp & Paper Processing: Serves as a chelant in bleaching processes to deactivate metal ions that can catalyze the decomposition of bleaching agents.
• Textile Treatment: Used in dyeing and finishing processes to complex with metal ions that may interfere with color uniformity and fabric quality.
• Laboratory Research: A key biochemical tool for studying metalloenzymes and calcium-dependent processes by selectively chelating specific cations.

Quality Control

Our Cdta is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets stringent specifications for purity, identity, and performance. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, heavy metal content, and loss on drying. Our quality commitment supports applications requiring high consistency, from pharmaceutical intermediates to analytical reagent grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed after each use to minimize exposure to atmospheric moisture, which can affect product quality and handling properties.
