About Potassium Iodide

Potassium lodide (KI) is the most widely recognized source of iodine for human nutrition. KI is highly susceptible to sublimation and oxidation, especially when exposed to moisture, light, or acidic environments. However our high-performance Potassium Iodide portfolio is engineered to solve the extreme volatility and s...

Public Health & Universal Salt Iodization (USI)

Primary active for preventing Iodine Deficiency Disorders (IDD). Our ME technology ensures the iodine remains stable even in low-grade salt, high-humidity environments, and during transport

Infant Nutrition & Formula

Critical micronutrient for Thyroid Hormone Synthesis and cognitive development. Micro-encapsulation ensures zero reaction with sensitive fats or proteins in the formula

Maternal & Prenatal Health

Essential for fetal brain development. Our 1% ME powder allows for high-precision microdosing in prenatal multivitamins

Pharmaceutical Manufacturing

Optimised for high tableting recovery (95–98%), ensuring the delicate iodide ions are not oxidised to molecular iodine (which causes discolouration) during the compression process. Food & Beverage Fortification: Used in the fortification of flour, milk, and condiments. The ME barrier prevents interaction with iron or other minerals that typically cause instability in premixes

Catalyst

A catalyst for the conversion of aromatic primary amines to nitro compounds, the conversion of aryl halides to aryl iodides, and the preparation of sulfonated oxindoles

Reducing Agent

A reducing agent for the reduction of graphene oxide in the presence of hydrochloric acid

Reagent

A reagent used in the preparation of standard iodide stock solutions for size exclusion chromatography and the spectrophotometric determination of advanced oxidation protein products

Material Synthesis Precursor

A precursor used as an additive to fabricate perovskite solar cells and light-emitting diodes to enhance stability and performance

Cathode Material

A cost-effective cathode material for efficient potassium-ion storage in batteries

Medication

A medication used to treat hyperthyroidism, protect the thyroid gland from radiation, and treat dermatological conditions like cutaneous sporotrichosis

Dietary Supplement

A nutritional supplement added to table salt and animal feed to prevent iodine deficiency

Expectorant

An expectorant used to loosen mucus and increase the water content of respiratory secretions

Scavenger

A scavenger of hydroxyl radicals to inhibit active oxygen and prevent DNA damage

Chaotropic Agent

A chaotropic agent used at high concentrations to dissolve gel matrices for the recovery of DNA from gel slices
