Import Diethylene Triamine Penta (Methylene Phosphonic — Buy in Bulk from Supplier in China

Diethylene Triamine Penta (Methylene Phosphonic), CAS 15827‑60‑8, has the molecular formula C9H28O15N3P5 and a molecular weight of 573.2 g mol‑1. The product appears as a yellow‑brown or red‑brown viscous liquid, contains 50.0 % active acid, 3.0 % phosphorus acid (as PO3³‑), 12‑17 % chloride (as Cl‑), and shows a density of 1.35‑1.45 g cm‑3 at 20 °C. In a 1 % solution the pH is around 2.0 and iron impurity is limited to 35 ppm.

The compound is recognised for its strong scale‑inhibition and corrosion‑protection abilities, especially in alkaline environments and at temperatures above 210 °C where it outperforms many organophosphines. Its solubility in acidic media is rapid, allowing easy dosing in circulating cooling‑water loops and boiler systems. Typical industry practice classifies it as an organophosphonate scale inhibitor, valued for temperature tolerance and compatibility with existing water‑treatment programmes.

End users such as power‑plant water‑treatment operators, oil‑field water‑recycle facilities, textile dyeing plants, paper manufacturers and cosmetics formulators commonly source this chemical. It is supplied in 25 kg plastic drums, with an optional IBC drum on request, and can be stored for up to ten months in a dry, shaded location.
