DTPA Acid
Diethylenetriaminepentaacetic Acid — High-Purity Chelating Agent for Micronutrient Manufacturing
Chelating Agent for Modern Fertilizer Formulations
DTPA Acid (Diethylenetriaminepentaacetic Acid) is a high-purity synthetic chelating agent used for binding metal ions and manufacturing chelated micronutrients.
With a minimum assay of 99.0% and strong metal-binding capability, DTPA Acid can be used as a chelating raw material for the production of iron, zinc, manganese, copper, and other metal complexes.
In agricultural manufacturing, DTPA is particularly relevant to the production of DTPA-chelated micronutrients, including DTPA-Fe used in specialty fertilizers, fertigation, hydroponics, and other crop nutrition formulations.
Unlike ready-to-use DTPA-5Na liquid solutions, DTPA Acid is supplied as a high-purity solid raw material, making it suitable for manufacturers that require greater control over neutralization, chelation reactions, concentration, and downstream formulation.
TerraNutrix supplies DTPA Acid for fertilizer manufacturers, micronutrient producers, and specialty formulation companies.
Key Benefits
High-Purity DTPA Raw Material
DTPA Acid provides ≥99.0% assay, making it a concentrated solid source of DTPA for manufacturers requiring a high-active-content chelating raw material.
Strong Metal-Binding Capability
DTPA is a multidentate chelating agent capable of forming complexes with various metal ions. For micronutrient manufacturers, relevant metals may include: Fe • Zn • Mn • Cu
Suitable for Controlled Chelation Processes
DTPA Acid gives manufacturers flexibility to control their own: Neutralization process; Reaction pH; Metal source; DTPA-to-metal ratio; Final nutrient concentration; Liquid or solid downstream formulation.
