Jinan Quicer Technology & Trade Co., Ltd provides 1‑Hydroxy Ethylidene‑1,1‑Diphosphonic Acid (HEDP) identified by CAS 2809‑21‑4. The supplied material appears as either a colourless to light‑yellow transparent liquid or a white crystal powder, with an active content of 58‑62 % by weight. The product’s molecular weight is 206.02 g mol‑1 and its density is approximately 1.40 g cm‑3. Impurities are limited to a maximum of 2.0 % phosphorous acid, 0.8 % phosphoric acid and 0.01 % chloride, meeting typical industry limits for water‑treatment chemicals.

HEDP demonstrates excellent scale inhibition up to 250 °C and retains performance at alkaline pH, resisting hydrolysis and decomposition. In solution, the pH of a 1 % preparation is limited to 2 max, and the product remains stable in the presence of chlorine oxidation. Typical dosage ranges from 1‑10 mg L‑1 for scale control, 10‑50 mg L‑1 for corrosion protection and 1000‑2000 mg L‑1 when used as a detergent in electronic cleaning. The solid form is supplied in 25 kg polyethylene‑lined bags within outer woven containers, while the liquid is packed in 250 kg plastic drums or IBC drums.
