Description

Triammonium Hydrogen Ethylenediaminetetraacetate is a water-soluble ammonium salt of the versatile chelating agent EDTA. This compound is valued for its ability to sequester di- and trivalent metal ions, forming stable, water-soluble complexes. It is essential for industries requiring precise metal ion control, such as analytical chemistry, pharmaceuticals, and industrial cleaning formulations. Its specific ammonium salt form offers advantages in pH-sensitive applications where solubility and compatibility are critical.

Application

• Analytical Chemistry Reagent: Used as a complexometric titrant and metal ion masking agent in titrations and spectrophotometric analyses.
• Pharmaceutical & Cosmetic Ingredient: Acts as a stabilizer and sequestrant in formulations to inactivate trace metal ions that can catalyze degradation.
• Industrial Cleaning & Descaling: A key component in formulations for removing limescale and metallic deposits from boilers, heat exchangers, and membranes.
• Agriculture & Micronutrient Fertilizers: Employed as a chelating agent in micronutrient supplements to enhance plant availability of metals like iron and zinc.
• Water Treatment: Used to control water hardness and prevent scale formation in cooling towers and industrial water systems.
• Laboratory Research: Serves as a buffer component and metal ion control agent in various biochemical and molecular biology research protocols.

Quality Control

Our Triammonium Hydrogen Ethylenediaminetetraacetate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, pH, and heavy metal content. Specifications can be aligned with general reagent or technical grade standards as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or changes in assay.
