Indol‑3‑yl‑Acetic Acid (IAA) – LR Grade, 1g

Indol‑3‑yl‑Acetic Acid, commonly abbreviated as IAA, is a well‑known plant growth regulator supplied here in a 1g pack suitable for educational laboratory use. Classified as Laboratory Reagent (LR) grade, this compound is ideal for controlled experiments and demonstrations in school science laboratories.

IAA is a naturally occurring auxin that plays a key role in plant growth and development, influencing processes such as cell elongation, root formation, and directional growth (tropisms). The product has a CAS Number: 87‑51‑4 and does not carry a UN number, indicating it is not classified as hazardous for transport when handled appropriately.

Supplied in a small quantity well suited to classroom experiments, Indol‑3‑yl‑Acetic Acid allows students to safely explore important biological principles while supporting clear observation and meaningful data collection.
