Product Overview
Ammonium dihydrogen orthophosphate (NH₄H₂PO₄), commonly known as ammonium phosphate monobasic, is a high-purity laboratory reagent grade chemical designed for precision applications in research and analytical chemistry. This crystalline powder offers exceptional water solubility, ensuring rapid dissolution and homogeneous solutions for buffer preparation, pH regulation, and phosphate-based reactions. With an assay purity of 98% or higher, it meets stringent LR grade standards, guaranteeing minimal impurities that could interfere with sensitive experiments. The compound’s stable chemical structure makes it a reliable choice for long-term storage without degradation, provided it is kept in a cool, dry environment away from moisture and incompatible substances. Its versatility extends to agricultural research, where it serves as a controlled nutrient source in plant studies, though its primary strength lies in its analytical consistency. The fine particle size ensures accurate weighing and dosing, reducing measurement errors in quantitative procedures. Whether used as a standalone reagent or as part of complex formulations, this ammonium phosphate monobasic delivers reproducible results, making it indispensable in laboratories demanding high accuracy and reliability.
FAQs
1. What is the solubility of ammonium phosphate monobasic LR in water?
Ammonium dihydrogen orthophosphate is highly soluble in water, with approximately 22.7 g dissolving in 100 mL at 20°C, forming a clear, colorless solution.
2. Can this product be used for preparing phosphate buffer solutions?
Yes, it is commonly used to prepare phosphate buffer solutions, particularly in the pH range of 5.8–7.4 when combined with disodium hydrogen phosphate.
3. Is this chemical compatible with strong oxidizing agents?
No, ammonium phosphate monobasic should not be stored or mixed with strong oxidizing agents, as it may lead to hazardous reactions or decomposition.
4. What is the shelf life of this LR-grade ammonium phosphate?
When stored in a tightly sealed container under cool, dry conditions, the product retains its stability and purity for up to 3 years from the date of manufacture.
5. Are there any alternatives to this product for similar applications?
Potassium dihydrogen phosphate (KH₂PO₄) can serve as an alternative for buffer preparation, though solubility and ionic strength may vary slightly in formulations.
