Product Overview
Potassium hydrogen phthalate (KHP) AnalaR NORMAPUR® is a high-purity, crystalline powder widely recognized for its stability and precision in laboratory applications. This reagent-grade compound is meticulously manufactured to meet stringent analytical standards, ensuring minimal impurities and consistent performance. Its non-hygroscopic nature makes it ideal for long-term storage without degradation, while its well-defined molecular weight (204.22 g/mol) enables accurate molar calculations in titrimetric analyses. The AnalaR NORMAPUR® certification guarantees compliance with international pharmacopeial standards, providing researchers with a reliable reference material for critical measurements. The compound’s excellent solubility in water (50 g/L at 20°C) facilitates easy preparation of standard solutions, while its resistance to atmospheric CO₂ absorption maintains solution stability over extended periods. This grade is particularly valued in primary standardization processes where absolute purity is paramount, offering a certified assay of ≥99.9% to eliminate systematic errors in quantitative analyses.
FAQs
1. What is the exact molecular formula of this potassium hydrogen phthalate?
The molecular formula is C₈H₅KO₄, representing one potassium ion, eight carbon atoms, five hydrogen atoms, and four oxygen atoms in its structure.
2. How does the AnalaR NORMAPUR® grade differ from standard laboratory grades?
