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

A background electrolyte for capillary electrophoresis containing tris(-hydroxymethyl) aminomethane (THAM) and ethanesulfonic acid (ESA) gives excellent efficiency for separation of drug cations with actual theoretical plate numbers as high as 300,000. However, the analyte cations often elute too quickly and
