Name: Potassium Iodate Diiodate
Chemical Formula: Often listed as KIO3(IO3)2
Common Uses: Acts as a reagent in laboratories, takes part in analytical chemistry, sometimes gets discussed in iodine supplementation discussions.
Form: Appears as a white crystalline powder, odorless, with a taste only someone in a lab would want to experience.
GHS Classification: Oxidizing solid, skin and eye irritant, hazardous if swallowed or inhaled
Hazard Statements: Increases risk of fire if in contact with combustible materials, can cause eye damage, may irritate skin, inhalation could cause coughing or sore throat.
Pictograms: Skull and crossbones, exclamation mark, oxidizer
Routes of Exposure: Skin contact, eye contact, swallowing, dust inhalation all count as ways it enters the body.
Main Ingredient: Potassium Iodate Diiodate
CAS Number: Most variants list 7758-05-6 for potassium iodate, no unique CAS for the double salt on major chemical references.
Purity: Lab-grade sources land above 99%.
Impurities: Small traces of potassium salts—these tend to stay below 0.5%.
Eye Contact: Rinse open eyes under water for several minutes, remove contact lenses if easy.
Skin Contact: Wash off with gentle soap and plenty of water; watch for rash or irritation.
Inhalation: Move out to fresh air, loosen tight clothing, seek care if breathing stays tough.
Ingestion: Rinse mouth with water, do not induce vomiting, medical advice is necessary.
Note: Allergic reactions call for immediate emergency help.
Suitable Extinguishing Media: Dry chemical, CO2, water spray work best. Regular foam is at risk due to the oxidizing nature.
Unsuitable Extinguishing Media: Never use dry combustibles; intensifies the burn.
Hazardous Decomposition: Generates toxic iodine fumes with heat.
Firefighter Protection: Use self-contained breathing apparatus and flame-resistant gear.
Personal Precautions: Wear gloves, goggles, a dust mask; reduce skin contact.
Environmental Precautions: Prevent lock on drains or streams, avoids contamination of groundwater.
Clean-Up Methods: Scoop up with care, sweep with a gentle damp broom, store in sealed waste containers for disposal.
Safe Handling: Avoid creating dust, use with ventilation, keep away from combustible materials, never return unused product to the main container.
Storage Conditions: Keep in a sealed, labeled container in a dry, cool place, away from light sources.
Incompatibilities: Organic substances, acids, reducing agents, and anything that might catch fire easily.
Engineering Controls: Use chemical fume hoods, proper ventilation in the lab or workspace.
Personal Protective Equipment: Gloves (nitrile or neoprene), safety goggles, lab coat, dust-proof mask.
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing straight away.
Appearance: White to colorless crystals or powder
Odor: No notable scent
Melting Point: Decomposes at high temperature, above 550°C
Solubility: Dissolves in water, remains stable in air
Density: Circa 3.98 g/cm3 for similar salts
pH (aqueous): Slightly acidic to neutral
Chemical Stability: Stable at room temperature, does not degrade quickly.
Hazardous Reactions: Powerful oxidizer, reacts fast with organic materials, reducing agents, acids.
Decomposition Products: Gives off iodine and oxygen at high heat or under strong acid presence.
Conditions to Avoid: Exposure to fire, sparks, or incompatible substances.
Acute Toxicity: Ingestion, even of modest amounts, causes nausea, stomach pain, vomiting.
Skin/Eye Irritation: Causes stinging, redness, possible chemical burns in sensitive eyes or broken skin.
Chronic Effects: Long-term exposure hasn’t had deep study, but repeated contact with strong iodine salts risks thyroid disruption.
Inhalation: Irritates nasal passages, coughs, sneezing if the powder gets airborne.
Aquatic Toxicity: Potassium iodate-based salts disrupt local aquatic life even though data is limited; iodine salts may bioaccumulate.
Persistence: Soluble in water, tends to hang around soils and sediments.
Environmental Fate: Breaks down into iodide and iodate over time, but high concentrations mean risk for algae or fish.
Disposal Method: Treat as hazardous chemical waste, send to licensed disposal contractors.
Avoid: Never dump down the drain or landfill—can pollute water sources and soil.
Container Handling: Decontaminate empty containers, destroy labels to avoid misidentification.
UN Classification: Usually listed as an oxidizer, grouped with potassium iodate in transit regulations.
Packaging: Seal tightly, label as an oxidizing agent, keep separate from flammables.
Precautions: Avoid impact and exposure to sunlight, transport under cool, dry conditions.
Hazard Codes: Classified under local and international codes for oxidizers.
Labelling Requirements: Must state hazards, safety advice, and pictograms clearly on package.
Restrictions: Not for public sale in large amounts, controlled access for lab or industrial use only.
Relevant Laws: Subject to chemical handling and transport laws worldwide, requires full documentation for shipping and usage.
