Zinc Disodium EDTA (CAS 14025-21-9) is a complex chemical compound with a molecular weight of approximately 399.6, making it a robust chelating agent with diverse applications. As a premier supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. offers this high-quality chemical, ensuring its reliability for various industrial and agricultural needs. Understanding its chemical properties is key to appreciating its broad utility.

Physically, Zinc Disodium EDTA presents as a white powder, characterized by its excellent solubility in water. This high solubility, often exceeding 1000 g/L at 20°C, is critical for applications requiring homogeneous solutions, particularly in liquid fertilizers and water treatment systems. Its bulk density, typically around 800-1000 kg/m3 (untapped), is also an important factor for handling and packaging. The specified quality standard, with zinc chelated at a minimum of 15%, guarantees its efficacy in delivering essential nutrients.

In agriculture, its primary function is to act as a chelated micronutrient foliar fertilizer. The chelating ability of EDTA ensures that zinc remains in a soluble form, readily absorbed by plants through their leaves and roots. This improved uptake directly contributes to enhanced plant growth, as zinc is vital for enzyme activity and hormone production. Specifically, it helps to increase chlorophyll content, thereby boosting the plant's photosynthetic capacity.

Beyond agriculture, its capacity to bind with metal ions makes it invaluable in other sectors. In water treatment, it helps remove or sequester problematic metal ions, improving water quality. In cosmetics, it acts as a stabilizer, preventing degradation and extending product shelf life by complexing with metal catalysts. For manufacturers looking to buy Zinc Disodium EDTA, sourcing from a reputable provider like NINGBO INNO PHARMCHEM CO.,LTD. ensures that these critical chemical properties are met, delivering consistent performance in every application. Its versatility underscores its importance as a foundational chemical in modern industry. It’s an essential component for any formulation aiming for optimal stability and biological availability of micronutrients.
