Indole-3-acetic Acid Powder 99% | ‘3-IAA’, ‘IAA’ | Plant hormone

Perhaps the best-known of the auxins (certainly it’s the most commonly occurring in nature), Indole-3-acetic acid (‘IAA’) is a growth hormone which is primarily produced in a plant’s bud and young leaf cells. More recently, it’s also been discovered to be produced by species of fungi and various environmental and (apparently beneficially) parasitical bacteria too.

A whitish crystalline solid which is artificially applied in varying amounts to greatly enhance general plant growth, ‘IAA’ is soluble in polar organic solvents (such as ethanol) but not water. It’s also known as ‘1H-Indole-3-acetic Acid’, ‘2-(1H-indol-3-yl)acetic Acid’, ‘2-(1H-indol-3-yl)ethanoic Acid’, ‘3-IAA’, ‘C10H9NO2’, ‘Heteroauxin’, ‘Indoleacetic Acid’ and ‘Indolylacetic Acid’.

While as of the time of writing there’s not much available research on any human toxicity, as with many other plant additives (and fertilisers, etc.), it’s always prudent to treat ‘IAA’ as potentially harmful if inhaled or otherwise ingested!

Why not try some botanical experiments on your favourite species?
