3-Indoleacetic Acid (IAA), scientifically known as indole-3-acetic acid, stands as one of the most important and abundant plant hormones, belonging to the auxin class. Its presence is vital for numerous growth processes within plants, influencing everything from cell division and elongation to the development of roots and fruits. Understanding its fundamental properties and diverse applications is crucial for leveraging its full potential in agriculture and horticulture.

Chemically, IAA is represented by the molecular formula C10H9NO2, with a molecular weight of 175.18400. It typically appears as a white to yellow-brown crystalline powder. While it possesses good stability under certain conditions, it is notably sensitive to light and can react with strong oxidizing agents, necessitating careful storage, ideally at -20°C. Its physical properties, such as a melting point of 165-169°C and a density of 1.354 g/cm3, are important parameters for its handling and formulation. Ensuring the material meets specific analytical standards for appearance, purity (≥99.0%), loss on drying (≤0.5%), and residue on ignition (≤0.2%) is key to guaranteeing its effectiveness as a plant growth regulator.

The primary application of 3-indoleacetic acid plant growth regulator lies in its ability to promote plant development. It is widely used to stimulate cell division, which is the basis for increasing plant biomass. Furthermore, its role in accelerating root formation is invaluable for propagation, helping cuttings to establish roots more quickly and successfully. In fruit production, the benefits of indole-3-acetic acid are evident in its capacity to increase fruit setting and prevent premature fruit drop, leading to higher yields and improved crop quality. Growers looking to buy 3-indoleacetic acid are often seeking these specific developmental benefits.

The reliable performance of IAA in these critical agricultural functions underscores the importance of sourcing it from reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. Their commitment to providing high-purity 2-(1H-indol-3-yl)acetic acid ensures that users receive a product that consistently meets stringent quality control measures. This attention to detail is vital for a compound that acts as a potent plant hormone, where slight variations in purity or composition can affect outcomes.

In essence, 3-Indoleacetic Acid is a versatile and essential plant hormone. Its broad spectrum of actions, from root initiation to fruit development, makes it a cornerstone in modern agricultural practices. By understanding its properties and ensuring the use of high-quality material, professionals can harness the power of IAA to cultivate healthier, more productive plants.
