3-Indolebutyric acid is a chemical with the molecular formula C12H13NO2.
The pure product is a white crystalline solid. Insoluble in water, the solubility in water at 20°C is 0.25g/L. Soluble in benzene, soluble in other organic solvents.
Its vapor and air can form explosive mixture, which may cause combustion and explosion in case of open flame and high heat energy.
Reacts with oxidants. Its vapor is heavier than air and can travel considerable distances in low places. In case of high heat, the internal pressure of the container will rise, and there is a danger of rupture and explosion.
It is a broad-spectrum indole plant growth regulator and a good rooting agent, which can promote the rooting of cuttings of herbs and woody ornamental plants.
It is often used for root soaking and transplanting of woody and herbaceous plants, which can accelerate root growth and improve the rooting rate of plants. It can also be used for soaking and dressing of plant seeds, which can improve the germination rate and survival rate.

3-Indolebutyric acid handling, storage and transportation
Operation Precautions
Isolate and control operations with adequate ventilation. Operators must undergo relevant professional training and strictly abide by the operating procedures.
It is recommended that operators wear filtering respirators (half masks), chemical safety goggles, anti-static work clothes, and rubber oil-resistant gloves.
Smoking is strictly prohibited, away from flammable sources and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapors from leaking into the workplace air.
Avoid contact with oxidizing agents and acids. Filling should control the flow rate to prevent the accumulation of static electricity.
When handling, it should be lightly loaded and unloaded to prevent damage to packaging and containers.
Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers can be hazardous residues.
Storage Precautions
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Storage temperature should not exceed 30°C. It should be stored separately from oxidants, acids, and edible chemicals, and should not be mixed.
Use explosion-proof lighting and ventilation. Prohibit the use of mechanical equipment and tools that are prone to sparks. Storage areas should be equipped with emergency release equipment and suitable containment materials.
Wrapping method
Small open steel drums; screw-top glass, iron-covered glass, plastic or metal drums (cans) outside ordinary wooden boxes; screw-top glass, plastic or plated with full bottom grate boxes, fibreboard boxes or plywood boxes tin steel drums (cans).
Shipping Precautions
During transportation, transportation vehicles should be equipped with fire-fighting equipment and leakage emergency treatment equipment of the corresponding variety and quantity. In summer, it is best to ship in the morning and evening.
The tank (tank) truck used for transportation should have a grounding chain, and a hole partition can be set in the tank to reduce shock and static electricity. It is strictly forbidden to mix and transport with oxidants, acids, edible chemicals, etc.
During transportation, avoid sunlight, rain and high temperature. During the stopover, keep away from fire, heat and high temperature areas.
The exhaust pipe of the vehicle carrying this item must be equipped with a flame arrestor, and the use of mechanical equipment and tools that are prone to sparks is prohibited during loading and unloading.
When transporting by road, drive according to the prescribed route and do not park in residential areas and densely populated areas. It is strictly forbidden to slip away during railway transportation. It is strictly forbidden to use wooden boats and cement boats for bulk transportation.
First aid
Skin Contact: Remove contaminated clothing and rinse with running water.
Eye Contact: Lift eyelids and flush with running water or saline. Seek medical attention.
Inhalation: Remove from site to fresh air. If breathing is difficult, give oxygen. Seek medical attention.
Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.
Emergency measures
Hazardous characteristics: its vapor and air can form explosive mixture, which can cause combustion and explosion in case of open fire and high heat energy. Reacts with oxidants. Its vapor is heavier than air and can spread over considerable distances in low places. In case of high heat, the internal pressure of the container will rise, and there is a danger of rupture and explosion.
Hazardous combustion products: carbon monoxide, carbon dioxide.
Fire fighting methods: Firefighters must wear gas masks and full-body fire suits to put out the fire in the upwind direction. Move containers from the fire to an open area whenever possible. Keep the fire container cool by spraying water until the fire is over.
Containers in fire must be evacuated immediately if they change color or if the safety pressure relief device makes a sound. Extinguishing media: water mist, foam, dry powder, carbon dioxide, sand.
