Triethylamine for HPLC is a tertiary amine widely used as a mobile phase modifier in high-performance liquid chromatography to improve peak symmetry and separation efficiency. It acts as a basic additive to adjust pH and enhance the solubility of acidic compounds. This reagent has a CAS number of 121-44-8, with the molecular formula (C2H5)3N and a molecular weight of 101.19. It is stored at ambient conditions but carries a "Danger" signal word due to its corrosive and flammable properties. Molekula supplies Triethylamine for HPLC from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
