Description

Iodine CAS NO 7553-56-2 is a lustrous, blue-black, non-metallic solid belonging to the halogen group. It is an essential element with significant industrial and biological importance due to its versatile chemical reactivity and biocidal properties. This product is critical for manufacturers in the pharmaceutical, chemical synthesis, and disinfectant industries, where it serves as a key intermediate, catalyst, and active ingredient.

Application

• Pharmaceutical Synthesis: A crucial starting material and catalyst in the production of iodinated contrast media, thyroid medications (e.g., levothyroxine), and various active pharmaceutical ingredients (APIs).
• Disinfectants & Antiseptics: Used in tinctures, povidone-iodine solutions, and surgical scrubs for its broad-spectrum antimicrobial efficacy against bacteria, viruses, and fungi.
• Chemical Manufacturing: Serves as a catalyst in organic synthesis (e.g., iodination reactions) and as a raw material for producing iodine derivatives like potassium iodide, methyl iodide, and iodophors.
• Animal Nutrition & Health: An essential trace element added to animal feed and salt licks to prevent iodine deficiency disorders and support metabolic health.
• Industrial Catalysis: Employed in the production of synthetic rubbers (e.g., butyl rubber) and as a stabilizer in the manufacture of nylon.
• Analytical Chemistry: Utilized in titration methods (iodometry) for quantitative analysis of various substances, including vitamin C and sulfites.
• Electronics: Used in the manufacture of polarizing filters for LCD displays and in metal halide lamps.
• Water Treatment: Applied for emergency disinfection of drinking water and in some specialized industrial water treatment processes.

Quality Control

Our Iodine is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and compliance with major pharmacopoeial standards, including USP, EP, BP, and JP. Every lot undergoes comprehensive analysis for purity, identity, and specified impurities. A detailed Certificate of Analysis (COA) documenting all test results is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong reducing agents, ammonia, and alkali metals. Due to its highly volatile nature, ensure containers are properly sealed to prevent sublimation and potential contamination.
