Overview
Calcium EDTA, also known as Calcium Disodium Ethylenediaminetetraacetate, is a chelating agent widely used in medical and industrial applications. It is particularly effective in binding heavy metals, making it valuable in treating metal poisoning and in various industrial processes. The compound is synthesized from ethylenediamine and sodium chloroacetate, resulting in a stable, water-soluble powder. Its ability to form stable complexes with metal ions underpins its utility in diverse fields, from healthcare to manufacturing.
Physical and Chemical Properties
Calcium EDTA appears as a white crystalline powder with high solubility in water. It decomposes before reaching a melting point, and its stability in aqueous solutions makes it suitable for medical and industrial use. Key chemical properties include its chelating ability, which allows it to bind divalent and trivalent metal ions. This property is harnessed in medical treatments for heavy metal poisoning, where it helps remove toxic metals like lead and mercury from the body.
Main Applications
In medicine, Calcium EDTA is primarily used as an antidote for heavy metal poisoning, particularly lead toxicity. It is administered intravenously to bind and facilitate the excretion of toxic metals. Industrially, it serves as a chelating agent in processes such as water treatment, food preservation, and textile manufacturing. Its ability to stabilize metal ions prevents unwanted reactions and degradation in various products.
Safety and Storage
Calcium EDTA should be stored in a cool, dry place, protected from light and moisture to maintain stability. Proper labeling and segregation from incompatible materials are essential. Safety precautions include wearing gloves and eye protection to avoid irritation. In case of exposure, rinse thoroughly with water and seek medical advice if necessary. Always comply with local safety regulations and disposal guidelines.
B2B Procurement Guide
When procuring Calcium EDTA, prioritize suppliers with verified certifications and a track record of quality. Key factors include purity levels, CAS number verification, and batch consistency. Bulk purchases often come with cost advantages, but ensure proper storage conditions to maintain product integrity. Request samples for testing and confirm compliance with industry standards such as USP or BP for medical-grade applications.
