What is Indole-3-Butyric acid CAS 133-32-4?
Functional positioning: IBA is an efficient rooting agent. When used in combination (such as +NAA), it can optimize the root structure and increase the survival rate of transplanting.
Safe application: Operate strictly in accordance with the concentration to avoid cytotoxicity caused by high doses. Further clinical verification is required for medical use.
Procurement Strategy:
For agricultural applications, select industrial grade (≥97%), and for scientific research/medicine, select high purity (≥99%).
Pay attention to green-certified products and follow the trend of environmental protection policies.
Future focus: Track the progress of gene editing and sustained-release technologies, and explore the potential of IBA in stress resistance (drought resistance, salt resistance)
Indole-3-Butyric acid CAS 133-32-4 Use
1. Mechanism of action
Promote root growth: Induce the formation of plant cuttings and root primordia, accelerate cell division and differentiation, and promote the development of adventitious roots and vascular bundle systems.
Synergistic effect: When compounded with naphthylacetic acid (NAA), it can complement the rooting effect (IBA induces fine root systems, while NAA induces thick root systems).
2. Application fields and methods
Agriculture and Horticulture
Applicable crops:
Woody: apple, peach, citrus, grape, poplar, metasequoia;
Herbs: Strawberry, carnations, chrysanthemum, rose, poinsettia.
Usage method:
The applicable scenarios of the concentration operation mode
Immersion method: 50-300 ppm, soak the base for 6-24 hours, for plants that are difficult to root (such as rhododendrons and camellias).
Quick immersion method: 500-1000 ppm, immerse the base for 5-8 seconds, suitable for plants that are prone to root growth (such as grapes and roses).
Dipping powder method: 0.1-0.3% powder, moisten the base and then dip the powder. Large-scale cutting operation.
Foliar irrigation/drip irrigation: Dilute 1-6 grams per mu before irrigation to enhance the root system of field crops.
(2) Pharmaceutical and food industry
Medicine: The derivatives have antibacterial, anti-inflammatory and anti-tumor potential (such as in the treatment of digestive system diseases);
Food: Natural additives, improving taste, preservative and antioxidant, but application must comply with safety limits.
Indole-3-Butyric acid CAS 133-32-4 safety
Toxicological data
Acute toxicity: Oral LD₅₀ >500 mg/kg in rats; Oral LD₅₀ in mice = 100 mg/kg (low toxicity).
Environmental risk: Low toxicity to aquatic organisms, but it is necessary to avoid polluting water sources.
2. Operation and Storage
Protective measures: Wear a lab coat and gloves during operation to avoid contact with skin/eyes.
Storage conditions: 2-8 °C, sealed in a dark place, away from oxidants and strong alkalis.
Transportation requirements: Protect from high temperatures and moisture. Do not use tools that can produce sparks for loading and unloading.
