n‑Butanol for HPLC is a high‑purity solvent specially prepared for chromatographic and analytical applications, providing low UV background, consistent retention times, and reliable reproducibility.
🏭⚗️ Production
Purified via multi-stage distillation to remove water, peroxides, and trace organic impurities. Quality-controlled for low UV absorbance, minimal conductivity, and batch-to-batch consistency. Packaged in airtight, solvent-resistant containers to prevent contamination and moisture uptake.
🔬 Properties
A clear, colorless liquid with a mild alcohol odor. Partially miscible with water and fully miscible with most organic solvents. Exhibits moderate viscosity, high chemical stability, and low UV absorbance. Hygroscopic; store tightly sealed in cool, dry conditions away from direct sunlight.
🧪 Applications
Used as a solvent and mobile-phase component in HPLC, sample preparation, and standard dilutions. Supports stable baselines, reproducible peak shapes, and consistent chromatographic performance in routine and specialized analyses.
⚠️ Safety
Flammable and harmful if inhaled, ingested, or absorbed through skin. Vapors may irritate eyes and respiratory tract. Handle with appropriate PPE in a ventilated area or fume hood. Keep away from heat, sparks, and oxidizing agents. Store in compatible, tightly closed containers.
