Product Overview
Sodium phosphate dibasic heptahydrate (99%+ purity) is a highly refined analytical reagent designed for precision laboratory applications. This crystalline powder offers exceptional solubility in water, making it ideal for preparing phosphate buffers, adjusting pH levels, and supporting biochemical reactions. Its high purity ensures minimal interference in sensitive assays, while the heptahydrate form provides stable hydration for consistent performance. The compound maintains excellent thermal stability and compatibility with most aqueous systems, allowing for reliable results across various experimental conditions. Its neutral pH in solution makes it particularly valuable for biological research where maintaining physiological conditions is critical. The analytical grade certification guarantees strict quality control, with impurities kept below detectable thresholds for most standard applications. This product comes in tightly sealed packaging to prevent moisture absorption and contamination during storage.
FAQs
1. What is the exact chemical formula of this dibasic sodium phosphate?
The chemical formula is Na₂HPO₄·7H₂O, representing disodium hydrogen phosphate with seven water molecules.
2. How should this product be stored to maintain its purity?
Store in a cool, dry place in its original tightly sealed container to prevent moisture absorption and contamination.
3. Is this compound compatible with common organic solvents?
It has limited solubility in most organic solvents but dissolves readily in water and glycerol solutions.
4. What’s the typical shelf life of this analytical-grade product?
When stored properly in unopened containers, it maintains its specified purity for at least 24 months from manufacture date.
5. How does this compare to anhydrous dibasic sodium phosphate?
This heptahydrate form contains water molecules in its crystal structure, making it more soluble but requiring adjustments when preparing solutions.
