General description
三丁胺（TBA）是一种作为强碱阴离子（SBA）交换树脂使用的叔胺。TBA也可作为低碳钢在HCL溶液中的缓蚀剂。此外，它可以在各种有机合成中被用作基础溶剂。
Application
三丁胺可用作：
- 一种含有CHCA（α-氰基-4-羟基肉桂酸） 的萃取溶剂，用于从EVOO（特级初榨橄榄油）和HO（榛子油）中选择性提取磷脂（PLs）。
- 合成尖晶石镍铁氧体（NiFe2O4）纳米粒子（NPs）的羟基化试剂。
Features and Benefits
在各种共沉淀方法中，三丁胺代替NaOH和NH4OH用作羟基化剂，因为它会导致pH值均匀升高，从而防止局部过饱和并促进整个溶液的均匀成核。

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

The influence of temperature on the efficiency of fluorescence of the encounter complex (A- ...D+)* in intermolecular electron transfer starting from neutral precursors has been studied. In contrast to what is generally assumed, fluorescence emission of the exciplexes is found

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
