Description

Indole-3-Acetic Acid (IAA) is the primary, naturally occurring auxin, a pivotal class of plant hormones that regulate growth and development. Its significance lies in its ability to stimulate cell elongation, division, and differentiation, making it a fundamental tool for controlled plant morphogenesis. This compound is essential for researchers in plant physiology, agrochemical formulators developing advanced plant growth regulators, and biotechnology firms focusing on tissue culture and synthetic biology applications.

Application

• Plant Tissue Culture: Used as a key growth regulator in media to induce callus formation, somatic embryogenesis, and root initiation.
• Agricultural Plant Growth Regulators (PGRs): A critical active ingredient or intermediate in formulations designed to promote rooting of cuttings, improve fruit set, and manage plant architecture.
• Plant Physiology & Biochemistry Research: Serves as a standard and experimental compound for studying auxin signaling pathways, tropisms, and developmental processes.
• Horticulture: Applied to enhance the propagation success of ornamental plants, trees, and vines through improved root system development.
• Seed Treatment: Incorporated into treatments to potentially improve germination vigor and early seedling growth under stress conditions.
• Biofertilizer & Biostimulant Enhancement: Used in combination with microbial inoculants to synergistically promote plant growth and nutrient uptake.

Quality Control

Our Indole-3-Acetic Acid is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards suitable for research and industrial applications. A Certificate of Analysis (COA) detailing specific results for purity, related substances, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect stability and handling properties.
