Product Overview
Magnesium sulfate heptahydrate LR is a versatile, high-purity inorganic salt widely used in laboratory settings for its excellent desiccant properties and role in chemical reactions. This crystalline powder, with a minimum purity of 98%, is ideal for applications requiring precise moisture control, such as drying organic solvents or stabilizing enzyme reactions. Its heptahydrate form ensures consistent solubility in water, making it suitable for crystallization processes and as a reagent in analytical chemistry. The LR (Laboratory Reagent) grade guarantees low impurity levels, ensuring reliable results in sensitive experiments. Whether used as a drying agent in organic synthesis or as a component in buffer solutions, this compound maintains stability under standard lab conditions. Store in a tightly sealed container to prevent moisture absorption, which can alter its efficacy. Compatible with most glassware and standard lab equipment, it integrates seamlessly into existing workflows without requiring specialized handling.
FAQs
1. What is the primary function of magnesium sulfate heptahydrate in labs?
It is primarily used as a drying agent to remove trace water from organic solvents and as a crystallization aid in chemical synthesis.
2. Can this be used as a substitute for anhydrous magnesium sulfate?
While both forms serve as desiccants, the heptahydrate version contains water molecules and is less efficient for drying compared to the anhydrous form.
3. How should this product be stored to maintain its purity?
Store in an airtight container in a cool, dry place to prevent hydration or clumping due to atmospheric moisture.
4. Is this grade suitable for food or pharmaceutical applications?
No, the LR grade is intended for laboratory use only and is not certified for food, pharmaceutical, or medical applications.
5. What is the typical shelf life of this product under proper storage?
When stored correctly, magnesium sulfate heptahydrate LR retains its efficacy for up to 2–3 years from the date of manufacture.
