1-Naphthaleneacetic acid, commonly abbreviated NAA, is an organic compound with the formula C₁₀H₇CH₂CO₂H. This colourless solid is soluble in organic solvents. It features a carboxylmethyl group (CH₂CO₂H) linked to the "1-position" of naphthalene.

Use and regulation

NAA is a plant hormone in the auxin family and is an ingredient in many commercial plant rooting horticultural products; it is a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture.

The hormone 1-Naphthyl acetic acid (NAA) does not occur naturally. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), products containing NAA require registration with the Environmental Protection Agency (EPA) as pesticides.
