Indole-3-acetic acid

Indole-3-acetic acid (CAS 87-51-4), commonly abbreviated as IAA, is the primary naturally occurring auxin. This class of plant growth hormones regulates cell elongation, root initiation, and developmental responses across virtually all plant species.

In commercial practice, it functions as a rooting agent and plant growth regulator in agricultural and horticultural applications. IAA is used in propagation programs to stimulate adventitious root formation in cuttings.

This reduces establishment time for ornamental, fruit, and forestry crops. In agricultural research and crop science, it serves as a reference standard for auxin activity studies and plant hormone quantification assays.

Pharmaceutical and biochemical manufacturers source IAA as an intermediate or reference compound in synthesis workflows targeting indole-derived molecules. It is a critical component for many laboratory applications.

Cosmetic formulators have incorporated it into scalp and hair care formulations targeting follicle stimulation. Its plant-derived origin supports naturals-positioning claims for high-end personal care products.

Indole-3-acetic acid is supplied as a white to off-white crystalline powder. It is available in technical grade for agricultural and research use, as well as high-purity grades meeting specific requirements.

Our material meets the specifications required by pharmaceutical and analytical customers. Packaging ranges from small research quantities to bulk orders to suit various industrial and laboratory needs.

Storage recommendations typically specify cool, dry conditions to maintain stability over time. We ensure that all batches are tested to meet rigorous quality and purity standards for our global clients.
