Import Ethylene Diamine Tetra (Methylene Phosphonic Aci — Buy in Bulk from Supplier in China

Ethylene Diamine Tetra (Methylene Phosphonic Acid), abbreviated EDTMPA, is supplied as a solid white crystal powder. The material bears CAS No 1429‑50‑1, molecular formula C6H20N2O12P4 and molecular weight 436.13 g mol‑1. According to the listing the product contains at least 95 % active acid, a minimum of 82 % total phosphonic acid expressed as PO4³‑, and a dryness weight loss not exceeding 2 %. Impurity limits are specified as a maximum of 5 ppm iron, 0.1 % chloride, and a pH of 2.0 or lower in a 1 % aqueous solution.

Such purity levels place the reagent in the high‑purity grade category commonly required for semiconductor cleaning and medical radio‑element preparation. In the broader market typical solid EDTMPA grades exhibit moisture contents below 5 % and solubility in water under 5 % at ambient temperature, matching the supplier’s note that the powder dissolves readily in ammonia. Standard practice stores the chemical in a cool, dry, shaded environment for up to twelve months, which aligns with the supplier’s one‑year shelf‑life claim. Typical packaging for bulk chemical reagents involves 25 kg inner‑liner polyethylene bags placed inside outer woven plastic sacks, a format the supplier also uses.

The chelating capacity of EDTMPA makes it valuable for semiconductor wafer detergents, as a carrier for radio‑isotopes in medical applications, and for inspection‑therapy agents. Buyers such as integrated‑circuit manufacturers, pharmaceutical radiochemistry firms and specialised cleaning services commonly source this reagent. The listing notes packaging in 25 kg PE bags with optional export‑environment agreements, but does not disclose minimum order quantities, lead times or incoterms, so prospects should confirm these trade details directly with the supplier. Prospective importers are advised to request a Certificate of Analysis and to verify storage conditions before finalising the purchase.
