    DESCRIPTION

    General description

    Triethanolamine (TEA) belongs to the family of ethanolamine. It includes the properties of both amines and alcohols.[1] Addition of TEA to an acidic buffer facilitates the determination of fluoride in inorganic orthophosphates by using a fluoride-selective electrode.[2]

    Application

    Triethanolamine (TEA) has been used:
    • as a component of the acetylation working solution[3]
    • in the preparation of polyethylene glycol (PEG) hydrogels[4]
    • as a constituent of CO2/O2 specificity (SC/O) assay buffer[5]
