Product Overview
This resublimed iodine from AnalaR NORMAPUR® is a high-purity ACS reagent grade chemical, rigorously tested to meet Pharmacopoeia Europaea (Ph. Eur.) standards. The sublimation process ensures exceptional purity by removing impurities, resulting in a crystalline solid with consistent performance in critical laboratory applications. Its precise molecular composition (I₂) guarantees reliable results in redox titrations, iodine value determinations, and other analytical procedures where accuracy is paramount. The product is packaged in airtight containers to prevent sublimation loss and maintain stability during storage. As an ACS-grade reagent, it adheres to strict specifications for heavy metals, non-volatile matter, and assay purity, making it suitable for quantitative analysis where trace impurities could affect outcomes. The AnalaR NORMAPUR® designation further confirms its suitability for high-precision work, with documented lot-specific certificates of analysis available for quality assurance.
FAQs
1. What is the difference between resublimed iodine and regular iodine?
Resublimed iodine undergoes an additional purification step where it is vaporized and recondensed, removing volatile impurities that regular iodine may contain. This process enhances its purity and consistency for analytical applications.
2. Can this iodine be used for Karl Fischer titration?
While iodine is a key component in Karl Fischer reagents, this pure crystalline form is not directly used. It requires preparation into a standardized solution with appropriate solvents and other reagents for Karl Fischer moisture analysis.
3. What is the typical shelf life of this product when stored properly?
When stored in its original, tightly sealed container away from light and moisture, this resublimed iodine maintains its specified purity for at least 3 years from the date of manufacture.
4. Is this iodine compatible with plastic containers for solution preparation?
Iodine solutions can degrade certain plastics over time. For long-term storage of iodine solutions, glass containers with PTFE-lined caps are recommended to prevent contamination and container deterioration.
5. How does the AnalaR NORMAPUR® certification benefit my experiments?
The AnalaR NORMAPUR® certification indicates this product meets exceptionally strict purity standards, with comprehensive testing for trace impurities that could interfere with sensitive analytical techniques, ensuring more reliable experimental results.
