Description

Dequest 2066, also known as diethylenetriaminepenta(methylenephosphonic acid) sodium salt (DTPMP.Na), is a phosphonate-based chelating agent with the molecular formula C₉H₂₈N₃O₁₅P₅·xNa and a molecular weight of approximately 1412.73 g/mol . It is typically supplied as a clear, viscous liquid or solid. Dequest 2066 is highly soluble in water and exhibits excellent thermal and chemical stability across a broad pH range. It functions as a strong chelating agent, effectively sequestering metal ions such as calcium, magnesium, and iron, which helps prevent scale formation and corrosion in various systems. The compound is generally considered non-toxic and biodegradable, aligning with environmental safety standards.
