General description
Tributylamine (TBA) is a tertiary amine used as strong base anion (SBA) exchange resin. TBA can also be used as a corrosion inhibitor for mild steel in HCl solution. Additionally, it can be used as a base solvent in various organic synthesis.
Application
Tributylamine may be used as:
- An extraction solvent with CHCA (α-cyano-4-hydroxycinnamic acid) for the selective phospholipids (PLs) extraction from EVOO (extra virgin olive oil) and HO (hazelnut oil).
- A hydroxylating agent in the synthesis of spinel nickel ferrites (NiFe2O4) nanoparticles (NPs).
Features and Benefits
In various co-precipitation methods, tributylamine is used as a hydroxylating agent instead of NaOH and NH4OH since it causes a uniform rise in pH which prevents local supersaturation and promotes homogeneous nucleation throughout the solution.

This study presents a systematic investigation of factors influencing the chromatographic separation of diastereomers of phosphorothioated pentameric oligonucleotides as model solutes. Separation was carried out under ion-pairing conditions using an XBridge C18 column. For oligonucleotides with a single sulfur substitution

Reverse-phase ion-pair high performance liquid chromatography (RPIP-HPLC) and ultra-performance liquid chromatography (RPIP-UPLC) are increasingly popular chromatographic techniques for the separation of organic compounds. However, the fine details of the RPIP separation mechanism are still being debated. Many factors including type
