Product Overview
Gadolinium(III) sulfate octahydrate from REacton™ is a high-purity rare earth compound, meticulously refined to 99.9% (REO) purity for demanding laboratory applications. This crystalline powder exhibits exceptional solubility in water and polar solvents, making it ideal for precise synthesis and analytical procedures. The octahydrate form ensures stability during storage and handling, while the REacton™ grade guarantees minimal impurities, critical for reproducible results in advanced research. Its unique magnetic properties, derived from gadolinium’s unpaired electrons, make it valuable in specialized applications requiring paramagnetic behavior. The compound’s consistent particle size distribution and low moisture content further enhance its reliability in quantitative analyses. Whether used as a reagent, catalyst, or calibration standard, this gadolinium sulfate delivers the performance required for high-stakes laboratory work where trace impurities could compromise outcomes.
FAQs
1. What is the solubility profile of this gadolinium sulfate octahydrate?
This compound is highly soluble in water (approximately 40 g/L at 20°C) and moderately soluble in polar organic solvents like ethanol. The octahydrate form dissolves completely in aqueous solutions without residual particles.
2. How does the REacton™ grade differ from standard laboratory grades?
The REacton™ designation indicates a minimum 99.9% rare earth oxide (REO) purity with strictly controlled trace metal impurities (typically <10 ppm for most common contaminants). This exceeds standard ACS reagent grades in consistency and batch-to-batch reliability.
3. What precautions should be taken when handling this powder?
While not classified as highly hazardous, standard laboratory precautions apply: use in a well-ventilated area, wear gloves/nitril to prevent skin contact, and avoid inhaling fine particles. The compound is non-volatile but may cause mild irritation to mucous membranes.
4. Can this be used as a replacement for gadolinium chloride in synthesis?
In most applications, yes, though the sulfate anion may require additional purification steps if chloride-free products are needed. The sulfate form offers better thermal stability during high-temperature reactions compared to hydrated chlorides.
5. What’s the typical shelf life when stored properly?
When kept in its original sealed container at room temperature (15-25°C) and protected from moisture, the product maintains its specified purity for at least 36 months. The octahydrate form is less hygroscopic than anhydrous alternatives.
