Description

Iodine (CAS 7553-56-2), also known as molecular iodine, is a halogen element supplied in solid form for industrial and pharmaceutical use. It functions primarily as a biocide and chemical intermediate. This material acts as a disinfectant across a broad range of manufacturing and treatment processes. In water treatment, it is used as an active disinfectant to eliminate bacteria, viruses, and protozoa.

It is essential for potable water systems and emergency purification applications. Pharmaceutical manufacturers use it as a key starting material for producing iodine-based antiseptics and contrast media. It is also utilized for thyroid-related active ingredients. In personal care formulations, it contributes antimicrobial activity to topical antiseptic products including wound care solutions and surgical scrubs.

The substance also serves as a reagent and oxidizing agent in specialty chemical synthesis and analytical laboratory processes. It is supplied as dark grey-black crystalline flakes or granules. These granules feature a characteristic metallic luster. Standard commercial grades include USP, BP, and Ph. Eur. for pharmaceutical and healthcare applications, alongside technical grade for industrial use.

Resublimed iodine is a recognized high-purity specification commonly required in pharmaceutical and analytical applications. This ensures the highest level of performance for sensitive chemical reactions.
