What it is / When to use

Chelated iron for fertigation, hydroponics, and foliar programs

EDTA-Fe-13 is a fully water-soluble iron EDTA chelate, formula C10H12N2O8FeNa·3H2O, CAS 15708-41-5, carrying chelated Fe 13% at pH 4-6. RunziChem exports it as a stable, readily available iron source that corrects iron chlorosis through drip irrigation, hydroponics, and foliar spray on neutral to slightly acidic soils.

  • What it is Iron EDTA chelate (EDTA ferric sodium salt), CAS 15708-41-5, brown-yellow to light-yellow powder.
  • When to use Use it for soluble iron in fertigation, hydroponics, liquid formulations, and foliar sprays; compare EDDHA-Fe for high-pH or calcareous soils above pH 7.
  • Honesty note specifications are typical for evaluation; final values are confirmed per batch COA.

Applications

Where EDTA-Fe-13 fits

Confirm crop, rate, compatibility, and local label requirements before application.

Iron chlorosis correction

Delivers chelated Fe 13% to correct iron chlorosis (leaf yellowing) across a wide range of neutral to slightly acidic soils.

Drip & fertigation

Fully water-soluble, so iron stays available in drip irrigation and water-fertilizer integrated systems without precipitating.

Hydroponics & soilless

A standard chelated iron for hydroponic nutrient solutions and soilless growing media.

Foliar & liquid formulations

Suited to foliar spray on flowers, fruit trees, and field and horticultural crops, and to liquid fertilizer blends.

Compare with EDDHA-Fe

On high-pH or calcareous soils above pH 7, compare EDDHA-Fe-6, which stays chelated where EDTA-Fe loses stability.

Batch documents

TDS, COA, and SDS support procurement and formulation review.

Buyer FAQ

EDTA-Fe-13 questions

When should I choose EDTA-Fe instead of ferrous sulphate or EDDHA-Fe?
EDTA-Fe-13 is a fully water-soluble iron chelate (chelated Fe 13%, CAS 15708-41-5) that stays stable in solution up to roughly pH 6.5, making it a cost-effective iron source for fertigation, hydroponics, and foliar sprays on neutral to slightly acidic soils. Ferrous sulphate is cheaper but not chelated and precipitates fast in irrigation. On high-pH or calcareous soils above pH 7, EDDHA-Fe stays chelated where EDTA-Fe loses stability.
What are the key specifications of RunziChem EDTA-Fe-13?
EDTA-Fe-13 is iron EDTA chelate, formula C10H12N2O8FeNa·3H2O, molecular weight 421.1, CAS 15708-41-5. It is a brown-yellow to light-yellow powder carrying chelated Fe 13%, with a 1% solution pH of 4-6, and it is fully water-soluble. These are typical values confirmed on the batch COA.
Can EDTA-Fe-13 be used in drip irrigation and hydroponic systems?
Yes. EDTA-Fe-13 dissolves completely in water and is a standard chelated iron source for drip irrigation and fertigation, hydroponic nutrient solutions, soilless media, liquid fertilizer formulations, and foliar sprays. Because it is chelated, iron stays available and does not precipitate the way a straight ferrous sulphate would in the same tank.
Is the 13% iron content guaranteed?
No. The chelated Fe 13% figure and the pH 4-6 range are typical values shown for buyer screening. The current batch certificate of analysis (COA) confirms the final chelated iron content, pH, appearance, and quality values for the lot you receive.
