Lab Pro Triethanolamine (TEA) is a reagent-grade organic compound supplied as a viscous liquid with a minimum assay of 98%. It contains both amine and hydroxyl functional groups, making it suitable for use as a buffer, emulsifier, and chemical intermediate in laboratory and research applications.
Triethanolamine is completely soluble in water and exhibits buffering capability within a useful pH range of 7.3 to 8.3. Its chemical structure supports a wide range of reactions and formulations where controlled pH adjustment, emulsification, or nitrogen functionality is required.
