Frequently Asked Questions
What is the full form of EDTA?
EDTA stands for ethylenediaminetetraacetic acid. The free acid is also called edetic acid; its common salts are disodium EDTA (EDTA-2Na) and tetrasodium EDTA. We supply EDTA in all these types as a white crystalline powder.
What is EDTA used for?
EDTA is a chelating agent — it sequesters metal ions in solution. Buyers use it as a detergent builder, in water treatment and scale control, textile processing, cosmetics and personal care, food and pharma chelation, and pulp and paper bleaching.
What is the CAS number of EDTA?
It depends on the salt type — one CAS number does not cover all forms. Free-acid EDTA is CAS 60-00-4, while the Di-Sodium dihydrate salt on our spec sheet is CAS 6381-92-6. Always match the CAS to the specific salt you are buying.
What is the difference between disodium EDTA and tetrasodium EDTA?
Both are sodium salts of ethylenediaminetetraacetic acid — they differ in sodium content and carry different CAS numbers. Our stocked spec sheet covers the Di-Sodium dihydrate salt (CAS 6381-92-6, technical grade), with a 1% solution pH of 4.0–6.0. We supply the free acid and tetra-sodium types as well.
What grade and purity of EDTA do you stock?
We stock Di-Sodium EDTA, technical grade, against the manufacturer's published BP/commercial-grade specification. Key values: assay 99.0–101.0% (EDTA-2Na, dried basis), chelation value 272 min mg/g as CaCO3, heavy metals 10 ppm max, iron 10 ppm max. It is a white crystalline powder with a clear, colourless 1% solution.
