Triethylamine for HPLC is a high-purity, analytical-grade organic amine widely used in pharmaceutical, biochemical, and analytical laboratories as a mobile phase modifier, pH adjuster, and ion-pairing reagent in HPLC and LC-MS applications.
🏭⚗️ Production
Produced through controlled synthesis and purification to remove trace metals, water, peroxides, and other organic impurities. Subjected to rigorous quality control to ensure consistent purity, low UV absorbance, and suitability for sensitive chromatographic applications. Packaged in chemically resistant, airtight containers to prevent contamination, moisture uptake, or degradation during storage and handling.
🔬 Properties
A clear, colorless to pale yellow liquid with a strong, characteristic amine odor. Miscible with water and most polar organic solvents. Exhibits basicity, high volatility, and chemical reactivity suitable for pH adjustment and ion-pairing in HPLC. Reactive with strong oxidizers and acids. Store in a cool, dry, well-ventilated area in tightly sealed, chemically resistant containers.
🧪 Applications
Used extensively in reversed-phase HPLC as a mobile phase additive to adjust pH, suppress tailing of basic analytes, and improve peak shape and reproducibility. Supports LC-MS workflows by facilitating ionization and maintaining consistent chromatographic performance. Applied in sample preparation, buffer preparation, and analytical method development requiring high-purity basic reagents. Ensures reliable, reproducible results in sensitive chromatographic analyses.
⚠️ Safety
Flammable, corrosive, and harmful if inhaled, ingested, or absorbed through the skin. May cause irritation to eyes, skin, and respiratory tract. Vapors can be harmful at high concentrations. Handle using appropriate PPE such as gloves, goggles, face protection, and lab coat in a well-ventilated area or fume hood. Keep away from heat, sparks, flames, and incompatible chemicals such as strong oxidizers and acids. Store in tightly closed, chemically resistant containers.
