Sodium Dihydrogen Phosphate for HPLC is a pharmacopeial-grade reagent designed for use in pharmaceutical, analytical, and laboratory applications requiring precise buffer preparation and highly reproducible chromatographic performance.
🏭⚗️ Production
Prepared under GMP- and pharmacopeial-compliant conditions using high-purity sodium dihydrogen phosphate (HPLC or analytical grade) dissolved in ultrapure water to achieve the exact concentration required for buffer preparation. The material is processed and handled in controlled environments to prevent particulate, ionic, or organic contamination. Packaged in chemically resistant, sealed laboratory containers to maintain integrity and prevent moisture uptake. Each batch is validated according to USP, EP, HPLC, and relevant reagent-grade standards to ensure purity, uniformity, and reproducibility.
🔬 Properties
A high-purity, white crystalline solid or ready-to-use clear, colorless aqueous solution (depending on form) with defined phosphate composition, excellent solubility, and stable buffering capacity within the acidic pH range. Exhibits strong chemical stability under recommended storage conditions. Minor changes in appearance or clumping may occur with exposure to moisture; gentle mixing or dissolution restores uniformity without affecting purity or analytical performance.
🧪 Applications
Used for preparation of mobile phases, buffer systems, pH adjustment, and analytical testing in pharmaceutical and research laboratories. Suitable for routine QC analysis, method validation, ionizable compound separation, and other HPLC procedures requiring a stable, precisely controlled phosphate buffer component.
⚠️ Safety
May cause irritation. Avoid ingestion, inhalation, and contact with skin or eyes. Use appropriate personal protective equipment, including gloves, goggles, and lab coat. Store in tightly sealed containers in a cool, dry environment to prevent moisture absorption. Dispose of according to laboratory, pharmacopeial, and environmental safety regulations.
