2-aminoethylphosphonic acid

CAS: 2041-14-7

Overview

2-Aminoethylphosphonic acid (CAS 2041-14-7 ), also known as ciliatine, is a naturally occurring phosphonic acid derivative used industrially as a chelating and sequestering agent.

It binds divalent and trivalent metal ions, allowing formulators to control trace metal activity in complex systems. In water treatment, it functions as a scale inhibitor and metal sequestrant.

This compound prevents calcium and magnesium deposits in industrial cooling and process water circuits. Agricultural formulations use it as a stabilizing additive to protect active ingredients.

It prevents metal-catalyzed degradation during storage and field application. Pharmaceutical and nutraceutical researchers source it as a reference compound or synthetic building block.

It is essential for phosphonate-containing active molecules. As a chelating agent in industrial cleaning and process chemistry, it helps prevent oxidative degradation triggered by free metal ions.

2-Aminoethylphosphonic acid is supplied as a white crystalline powder. Technical and research grades are the most commonly available, with purity specifications typically ranging from 97% to 99%+.

Packaging is available in small laboratory quantities through to bulk industrial orders. We provide full documentation support for regulated industries to ensure compliance with global standards.
