VWR Potassium Chloride (KCl), AnalaR NORMAPUR® Reag. Ph. Eur., is a high-purity reagent with an assay range of 99.5–101.0%, conforming to European Pharmacopoeia (Ph. Eur.) standards. This white crystalline solid is ideal for analytical chemistry, buffer preparation, physiological studies, and pharmaceutical manufacturing processes that require strict control of ionic strength and high-grade materials.
Key Features and Benefits
- Meets Reag. Ph. Eur. and AnalaR NORMAPUR® standards for quality and compliance
- High-purity assay range of 99.5–101.0% (on dried basis)
- Low levels of trace elements and heavy metals ensure analytical reliability
- Broad pH range compatibility (5.0–8.0) for flexible buffer formulations
- Stable and non-hygroscopic; easy to handle and store
Applications
- Preparation of physiological and isotonic solutions
- Standard electrolyte in analytical and clinical chemistry
- Buffering and pH control in biochemical assays
- Reagent in pharmaceutical quality control and formulation
- Calibration and titration standards in laboratory settings
