1-Naphthaleneacetic acid /NAA

1-Naphthaleneacetic acid, pure white crystal, odorless and tasteless, melting point of 130 ℃, easily soluble in organic solvents such as acetone, ether, benzene, ethanol and chloroform, almost insoluble in cold water, with a solubility of 0.024g/100g in water at 20 ℃, soluble in hot water, with good salt water solubility, stable structure and good storage resistance. Low toxicity.
1-Naphthaleneacetic acid, also known as naphthylacetic acid or α – naphthylacetic acid, is a broad-spectrum plant growth regulator with physiological effects and mechanisms similar to indoleacetic acid. It can promote cell division and expansion, induce adventitious root formation, increase fruit setting, prevent fruit drop, and alter the ratio of female to male flowers. It can enter the plant through the tender epidermis and seeds of leaves and branches, and be transported throughout the plant with nutrient flow.
