Calcium Iodide Hydrate is a specific crystalline hydrate form of calcium iodide, with the chemical formula CaI₂·4H₂O. This product is particularly suitable for applications requiring relatively broad moisture control and emphasizing cost-effectiveness, owing to its defined crystalline water content and enhanced physical stability.
We consistently supply well-crystallized calcium iodide tetrahydrate powder meeting standard specifications, particularly for routine chemical reagents. For specific requirements in this area, contact us for detailed information.
Fixed crystalline water content
Significantly reduced hygroscopicity compared to anhydrous forms
Simplified handling and storage
High biological bioavailability
Routine Chemical & Educational Reagents: A fundamental iodide reagent widely used in university, research institute, and industrial laboratories for most teaching experiments and routine synthetic reactions.
Specific Pharmaceutical Industrial Raw Material: Used to synthesize certain pharmaceutical intermediates where crystalline water form imposes no strict limitations, offering a more cost-effective process option.
Industrial Auxiliaries and Additives: Can serve as additives in specific chemical reaction systems or as intermediate raw materials for preparing other iodide compounds.
Q1: From an application perspective, how should one choose between calcium iodide tetrahydrate and calcium iodide anhydrous?
A1: If your process is sensitive to trace moisture (e.g., anhydrous synthesis), choose the anhydrous form. For applications insensitive to moisture, such as animal feed or routine reagents, the tetrahydrate is preferred due to its greater stability and cost-effectiveness.
Q2: How do you ensure accurate and consistent crystalline water content in each batch?
A2: We maintain consistent crystal morphology by controlling crystallization conditions. Each batch undergoes crystalline water content verification via methods like thermogravimetric analysis (TGA) to confirm compliance with the theoretical value for CaI₂·4H₂O.
Q3: Does this product still require moisture-proof storage?
A3: Yes. Although its hygroscopicity is lower than the anhydrous form, it remains a deliquescent substance. We recommend using the product promptly after opening the sealed packaging and storing it in a dry environment to maintain optimal flowability.
Each batch is supplied with:
Certificate of Analysis (COA)
Technical Data Sheet (TDS)
Material Safety Data Sheet (MSDS)
Third-party testing reports available upon request
