Iodine

Iodine (CAS 7553-56-2, EC 231-442-4, formula I2) is a halogen element supplied as grey to purple rounded solid particles. It is also known by the names Jod, Jood, Iode, Iodum, and Iodio across European markets. No E-code designation applies to this substance.

In pharmaceutical and water treatment applications, iodine acts as a broad-spectrum antimicrobial by oxidising microbial cell components, disrupting membrane integrity and enzyme function. It is used in antiseptic formulations, iodophor disinfectants, and potable water purification systems where controlled dosing delivers reliable pathogen reduction.

Iodine is available in pharmaceutical-grade form compliant with Ph.Eur. monograph standards, as well as technical grades for industrial water treatment use. It falls under REACH regulation and is classified under HS code 28012000. Packaging formats vary by volume; buyers should confirm grade specifications and compliance documentation at the point of enquiry.
