Bis(2‑ethylhexyl) hydrogen phosphate, 2‑methylundecan‑2‑amine (CAS: 68966‑86‑9) is an amine phosphate salt formed by the neutralization of bis(2‑ethylhexyl) phosphoric acid (also known as di(2‑ethylhexyl) phosphoric acid, D2EHPA) with 2‑methylundecan‑2‑amine (a branched C12 tertiary amine). The compound has the molecular formula C₂₈H₆₂NO₄P and a molecular weight of 507.77 g/mol. It appears as a colorless to pale yellow viscous liquid, soluble in organic solvents such as ether and dimethylformamide. Chemically, it is a long‑chain alkyl phosphate amine salt that combines the strong hydrogen‑bonding and metal‑chelating properties of the phosphate group with the steric bulk and hydrophobic character of the branched alkyl amine counterion.
CAS 68966-86-9 is also known in the fragrance industry under the name Mahagonate (methyl 4(or 1)‑isopropyl‑1(or 4)‑methylbicyclo[2.2.2]oct‑5‑ene‑2‑carboxylate, molecular formula C₁₄H₂₂O₂, molecular weight 183.25 g/mol). It is important to note that the same CAS number is used for both the phosphate‑amine salt and the fragrance ingredient; the substance described herein is the amine phosphate salt variant, which is supplied as a stable liquid for industrial applications.
The unique architecture of this compound — a bulky phosphate anion paired with a branched, sterically hindered ammonium cation — provides a distinctive combination of properties: excellent solubility in non‑polar and moderately polar organic media, strong hydrogen‑bond donation and acceptance capabilities, resistance to hydrolysis, and the ability to function as both an acid scavenger and a phase‑transfer agent. These characteristics position bis(2‑ethylhexyl) hydrogen phosphate, 2‑methylundecan‑2‑amine as a versatile additive in industrial formulations and a valuable intermediate in specialty chemical synthesis. Market demand is closely linked to the global lubricant additives industry, metal extraction and solvent refining sectors, and the expanding specialty chemical manufacturing base in Asia‑Pacific.

Core Application Fields and Demand
Market demand for bis(2‑ethylhexyl) hydrogen phosphate, 2‑methylundecan‑2‑amine is concentrated in three major sectors: industrial lubricant additives and corrosion inhibitors (≈40‑45% of global consumption), solvent extraction and metal refining reagents (≈30‑35%), and specialty chemical intermediates (≈15‑20%), with additional demand from agrochemical formulations and polymer processing (≈5‑10%).
In the industrial lubricant and corrosion inhibitor sector, the compound functions as a multifunctional additive in metalworking fluids, hydraulic oils, and rust‑preventive formulations. The phosphate moiety provides strong adsorption to metal surfaces, forming a protective film that inhibits corrosion and reduces friction, while the bulky amine counterion enhances oil solubility and thermal stability. The compound is particularly effective in high‑temperature and high‑pressure applications where conventional phosphate esters may hydrolyze or decompose. The global industrial lubricant additives market, valued at approximately USD 16‑18 billion in 2025, continues to expand at 3‑4% annually, supporting steady demand for high‑performance phosphate‑amine additives.
In the solvent extraction and metal refining sector, bis(2‑ethylhexyl) hydrogen phosphate, 2‑methylundecan‑2‑amine serves as a synergistic extractant for the recovery of rare earth elements, uranium, and transition metals from aqueous solutions. The phosphate group acts as a chelating agent for metal cations, while the amine counterion can be exchanged with metal ions under controlled pH conditions. This dual functionality enables selective separation of valuable metals from complex leach solutions in hydrometallurgical processes. The growing demand for rare earth elements in electronics, renewable energy technologies, and defense applications — with the global rare earth market projected to exceed USD 12‑15 billion by 2030 — drives sustained demand for high‑purity solvent extraction reagents.
In specialty chemical synthesis, bis(2‑ethylhexyl) hydrogen phosphate, 2‑methylundecan‑2‑amine is used as an acid scavenger and a phase‑transfer catalyst in organic reactions. Its ability to neutralize acids while maintaining solubility in organic media makes it useful in polymerization reactions, esterification processes, and the synthesis of pharmaceutical intermediates.
