Iodine (I2) Supplier in Malaysia
- Also known as
- Molecular Iodine
- I2
- Resublimed Iodine
- Elemental Iodine
Iodine supplier for pharmaceutical, laboratory, manufacturing and animal-feed buyers in Malaysia. Elemental iodine, also called molecular iodine or I2, is a purple-black lustrous solid that sublimes readily and is traded mainly as resublimed crystals, technical crystals or flakes, and free-flowing prills.
Resublimed grades are selected where high purity matters for synthesis, antiseptic or iodophor manufacture and laboratory reagent work. Technical crystal and prilled forms serve industrial production of metal iodides, catalysts, dyes, photographic chemistry and other process uses. Assay, form and residual limits should be stated against the process specification.
Pharmaceutical manufacturers use iodine as a starting material for iodine-containing intermediates and topical preparations. Laboratories use it in iodometric analysis and synthesis. Industrial plants manufacture iodides and related process chemicals from it, and formulators may specify elemental iodine for selected animal-feed additive intermediates.
Send the required grade or form, assay or specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Iodine grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Resublimed iodine crystals | purple-black lustrous crystals | typical high-purity resublimed grades commonly specified at ≥ 99.5% | Pharmaceutical synthesis, antiseptic and iodophor manufacture, and laboratory reagent work where a high-purity crystalline grade is preferred. | Confirm the required pack format with the quotation. |
| Technical iodine crystals | purple-black crystals or flakes | — | Industrial manufacture of iodides, catalysts, dyes, photographic chemistry and other process uses where a technical crystal grade is suitable. | Confirm the required pack format with the quotation. |
| Prilled or bead iodine | free-flowing prills or beads | — | Bulk handling and dosing where free-flowing solid form is preferred over conventional crystals or flakes. | Confirm the required pack format with the quotation. |

Iodine applications
Safety and handling
- Classification
- harmful
Keep sealed in a cool, dry, well-ventilated place away from incompatible materials. Iodine sublimes and can stain skin and surfaces; handle with appropriate protective equipment and follow the safety information for the quoted grade.
Common questions about iodine
What grades of iodine can buyers request?
Common market options include resublimed iodine crystals for higher-purity pharmaceutical and laboratory work, technical crystal or flake grades for industrial manufacture, and free-flowing prilled or bead forms for bulk handling. State the grade, form and assay needed with the enquiry.
Are molecular iodine, elemental iodine and resublimed iodine the same product?
Molecular iodine and elemental iodine both refer to I2. Resublimed iodine is a purified crystalline grade of the same element, produced by sublimation to raise purity and reduce non-volatile residue. The grade and assay still need to match the process specification.
What specifications should an iodine enquiry include?
Provide the intended application, preferred form (crystals, flakes or prills), target assay, any impurity or residue limits, quantity and delivery location. If a finished formulation already runs on a fixed grade, include that specification or a representative sample requirement.
Is iodine used only in pharmaceuticals?
No. Alongside pharmaceutical and antiseptic manufacture, elemental iodine is used in laboratory reagent work, industrial iodide and catalyst manufacture, photographic chemistry, dyes and selected animal-feed additive intermediates. Describe the end use so the grade can be matched more closely.
Can packing and documentation be confirmed with the quotation?
Yes. List any preferred pack format and required product documents in the enquiry. Available packing, documentation and commercial details are confirmed for the quoted grade.
What details are needed for an iodine price enquiry?
Send the grade or form, assay or specification, quantity and delivery location. Mention documentation needs and required timing so the quotation can address the complete requirement.
