Potassium hydrogen phthalate for HPLC

Potassium Hydrogen Phthalate for HPLC is a high‑purity, analytical‑grade reagent used in pharmaceutical and analytical laboratories for HPLC mobile phase standardization, pH calibration, and as a primary standard in titrations.

🏭⚗️ Production
Prepared from ultra‑pure potassium hydrogen phthalate salt under strictly controlled conditions to minimize trace metals, moisture, and other contaminants. Standardized for assay, particle size, and solution stability. Supplied in chemically resistant, tightly sealed containers to prevent contamination, moisture uptake, or degradation.

🔬 Properties
A white, crystalline solid, odorless, and non-hygroscopic under normal laboratory conditions. Highly soluble in water, chemically stable, and suitable for precise pH calibration and standardization in HPLC applications. Non-reactive with most solvents and reagents used in analytical laboratories. Store in a cool, dry, well-ventilated area in moisture-resistant containers.

🧪 Applications
Used in pharmaceutical and analytical laboratories for preparing HPLC mobile phases, calibrating pH meters, and as a primary standard for acid-base titrations. Ensures reproducible and accurate analytical results in aqueous and mixed solvent systems. Solutions and equipment should be handled carefully to maintain analytical-grade purity.

⚠️ Safety
Non-corrosive and generally considered safe under normal laboratory conditions. May cause mild irritation to eyes or respiratory tract if inhaled as dust. Use standard laboratory protective equipment including gloves, goggles, and lab coat. Avoid ingestion and excessive dust generation. Store in a tightly closed container in a cool, dry, well-ventilated area away from incompatible substances.
