EDTA Ferric Monosodium Salt (CAS 15708-41-5) is a stable iron(III)-EDTA chelate supplied as a crystalline solid. It is widely used in biochemical, agricultural, and industrial applications for its ability to chelate iron(III) and prevent enzyme inhibition caused by trace heavy metals.
With an assay of 66–71% EDTA and 12.5–14.0% Fe(III), this compound provides a reliable and consistent source of iron in controlled chelated form. It is commonly employed in buffer systems, enzyme studies, and as a micronutrient supplement in plant tissue culture and fertilizers.
Key Features
- High-quality chelating agent – stable iron(III)-EDTA complex.
- Assay guaranteed – EDTA 66–71%; Fe(III) 12.5–14.0%.
- Low impurity profile – chloride ≤0.05%, sulphate ≤0.2%, arsenic ≤3 ppm, lead ≤10 ppm.
- Versatile applications – biochemistry, agriculture, and industrial chemistry.
- Safe packaging – supplied in durable plastic bottles for solids.
Applications
- Biochemistry & Enzymology: Prevents heavy-metal inhibition of enzymatic reactions and inactivates divalent cation-dependent enzymes.
- Molecular Biology: Used in buffer systems for nucleic acid and protein stability.
- Plant Science & Agriculture: Iron micronutrient supplement in fertilizers and plant culture media.
- Industrial Chemistry: Chelating agent in formulations requiring stable iron complexes.
