<p>Applications An antibacterial drug. Sulfonamide antibiotic that blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase.This compound is a contaminant of emerging concern (CECs).<br>References Rudy, B.C., et al.: Anal. Profiles Drug Subs., 2, 467 (1973), Wormser, G.P., et al.: Drugs, 24, 459 (1982), Wharton, M., et al.: Ann. Intern. Med., 105, 37 (1986),<br></p>

<p>Applications Triethylamine is used as a competing base for the separation of acidic basic and neutral drugs by reverse-phased high-performance liquid chromatography (HPLC). Triethylamine induces visual disturbances (such as foggy vision) in humans (1), and is also used in industry as a quenching agent in the ozonolysis of alkenes (e.g. (E)-2-Pentene [P227315]). Triethylamine is used in the purification of drugs which are pharmacologically or chemically similar through separation in reverse-phase HPLC (2).Drinking water contaminant candidate list 3 (CCL 3) compound as per United States Environmental Protection Agency (EPA).
