Product Overview
Manganese(II) chloride, UltraDry™ grade, delivers exceptional purity at 99.998% (metals basis), making it indispensable for applications demanding minimal moisture interference. This anhydrous crystalline powder is meticulously processed to eliminate trace water content, ensuring consistent performance in sensitive reactions. The UltraDry™ designation guarantees a moisture level below 50 ppm, critical for electrochemical studies and catalysis where hydration can alter reaction pathways. Its high solubility in polar solvents like water and ethanol facilitates uniform dispersion in synthetic protocols. The product’s low impurity profile—with controlled levels of iron, copper, and other transition metals—prevents side reactions that could compromise experimental integrity. Packaged under inert conditions, it maintains stability during storage and handling. Whether used as a precursor in organometallic synthesis or as an electrolyte component, this grade offers reproducibility and precision, reducing variability in research outcomes. The fine particle size distribution enhances dissolution rates, while the absence of hydrates ensures accurate stoichiometric calculations. For laboratories prioritizing traceability, each batch undergoes rigorous ICP-MS analysis to verify metal purity, with certificates of analysis provided for quality assurance.
FAQs
1. What is the difference between UltraDry™ and standard anhydrous manganese(II) chloride?
The UltraDry™ grade undergoes additional drying processes to achieve moisture levels below 50 ppm, whereas standard anhydrous grades typically contain 100–500 ppm water. This makes UltraDry™ more suitable for moisture-sensitive applications like Grignard reactions or lithium-ion battery research.
2. Can this product be used directly in aqueous solutions without further purification?
Yes, the 99.998% purity (metals basis) ensures minimal impurities that could interfere with aqueous systems. However, if your protocol requires ultra-low levels of specific contaminants (e.g., alkali metals), pre-treatment with ion-exchange resins may be advisable.
3. How should this product be stored to maintain its anhydrous state?
Store in a tightly sealed container under an inert atmosphere (argon or nitrogen) with desiccant packs. Avoid exposure to ambient humidity, and use a glove box or dry environment during handling to prevent hydration.
4. Is this manganese(II) chloride compatible with organic solvents like THF or acetone?
It is soluble in polar organic solvents such as ethanol and methanol but has limited solubility in non-polar solvents like THF or acetone. For homogeneous solutions in these solvents, consider using manganese(II) chloride tetrahydrate or a solvent mixture.
5. What alternatives exist if I need a lower-purity grade for cost-sensitive applications?
For applications where ultra-high purity isn’t critical, consider manganese(II) chloride anhydrous (99%–99.5% purity) or the tetrahydrate form (98%+ purity). These are more economical but may introduce moisture or trace metal contaminants.
