二乙三胺五乙酸铁钠 (CAS No.19529-38-5)
- 中文别名
- 铁钠DTPA；DTPA铁钠盐；二亚乙基三胺五乙酸铁钠；乙二胺四乙酸铁钠类似物（DTPA铁钠）
- 英文名称
- Disodium iron(III) pentetate
- 分子式
- C14H18FeN3NaO10
- 所属类别
- 农药化肥原料
- 物化性质
- 黄棕色或浅黄色结晶粉末，易溶于水，水溶液呈浅黄色。作为金属螯合剂，对铁离子具有优异的络合稳定能力，在酸性和碱性介质中均能保持较好的稳定性。固体形态吸湿性较小，但水溶液在高温或强光照条件下可能缓慢分解。
- 技术参数
- 含量（以C14H18FeN3NaO10计）≥98.0% 铁（Fe）含量为10.5%~12.0% pH值（1%水溶液）为3.0~5.0 水不溶物≤0.1% 干燥失重≤1.0%
English description（英文原文，共 1155 字符）
Product Name:Disodium iron(III) pentetate
English Name:Disodium iron(III) pentetate
CAS No.:19529-38-5
Aliases:Iron sodium DTPA, DTPA iron sodium salt, Iron(III) pentetate disodium, Ferric DTPA disodium
Molecular Formula:C14H18FeN3NaO10
Physical Properties:Yellow-brown or light yellow crystalline powder, readily soluble in water, forming a light yellow aqueous solution. As a metal chelating agent, it exhibits excellent complexation stability for ferric ions and remains stable in both acidic and alkaline media. The solid form has low hygroscopicity, but aqueous solutions may slowly decompose under high temperature or intense light.
Uses:Used as a chelating agent in agriculture as a micronutrient supplement to provide absorbable iron to plants. It is also applied in water treatment, textile dyeing, and chemical analysis as a complexing masking agent for ferric ions. In the pharmaceutical field, it serves as an intermediate for iron supplement formulations.
Technical Specifications:
Assay (as C14H18FeN3NaO10) ≥98.0%
Iron (Fe) content: 10.5%~12.0%
pH (1% aqueous solution): 3.0~5.0
Water-insoluble matter ≤0.1%
Loss on drying ≤1.0%
