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
