In the realm of scientific research and laboratory analysis, the purity of reagents is non-negotiable. Iodine Crystals, specifically with CAS number 7553-56-2, are a fundamental chemical compound used in a variety of analytical procedures, titrations, and synthesis experiments. For laboratory managers and research scientists, sourcing high-quality iodine crystals from a dependable manufacturer is paramount to achieving accurate and reproducible results.

Understanding Iodine Crystals (CAS 7553-56-2)

Iodine (I2) is a nonmetallic chemical element characterized by its lustrous, deep violet, metallic appearance when solid. Its crystalline form, particularly at high purity levels, is sought after for its reactivity and predictable behavior in chemical reactions. The CAS number 7553-56-2 specifically refers to elemental iodine, distinguishing it from its salts or compounds.

Key properties that make high-purity iodine crystals valuable in laboratories include:

  • High Reactivity: Iodine is a strong oxidizing agent and participates in a wide range of chemical reactions, making it useful in synthesis and analytical chemistry.
  • Sublimation: Its ability to sublime allows for purification and its use in certain gas-phase reactions or analytical techniques.
  • Titration Reagent: Iodine is a key component in redox titrations, such as iodometry and iodimetry, commonly used for determining the concentration of various substances.
  • Analytical Standards: High-purity iodine crystals serve as primary standards for calibrating analytical instruments and validating methods.

Sourcing High-Purity Iodine for Laboratories

When purchasing Iodine Crystals for laboratory use, consider the following:

  • Grade of Purity: Look for analytical grade (AR) or reagent grade (RG) iodine. These grades are specifically manufactured and tested to meet the stringent purity requirements for laboratory work.
  • Certificate of Analysis (CoA): Always request a CoA that details the purity, presence of impurities (e.g., moisture, other halogens), and analytical methods used for verification.
  • Supplier Reputation: Partner with established chemical suppliers known for their quality control and reliable product offerings.
  • Packaging: Iodine crystals should be supplied in well-sealed containers to prevent contamination and degradation from light and moisture.

Finding a Reliable Supplier in China

China hosts a robust chemical manufacturing sector, providing access to a wide range of reagents. When seeking to buy Iodine Crystals, it is beneficial to work with experienced suppliers who understand the specific needs of research laboratories:

  • Wholesale Availability: Many suppliers offer competitive pricing for bulk purchases, which can be cost-effective for laboratories with regular needs.
  • Technical Documentation: Access to safety data sheets (SDS) and CoAs is essential for laboratory safety protocols and experimental planning.
  • Customer Service: Responsive customer service can assist with inquiries regarding product specifications, availability, and shipping.
