Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. Mutation data reported. A skin, mucous membrane, and severe eye irritant. Can cause depression. A pesticide, When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

1-Naphthaleneacetic acid is a carboxylic acid plant growth regulator used for thinning fruit sets in apples, pears, olives, and some citrus. Induces root formation on cuttings and transplants. Inhibits fruit drops. Not currently registered in EU countries (may be pending).

Shipping

UN1759 Corrosive solids, n.o.s., Hazard Class: 8; Labels: 8-Corrosive material, Technical Name Required.

Purification Methods

Crystallise the acid from EtOH or water. [Beilstein 9 H 666, 9 IV 2424.]

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, chlorates nitrates, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, epichlorohydrin. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic, and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur).

Waste Disposal

Incineration. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers.

uses

1-Naphthaleneacetic acid is widely employed in agriculture as a synthetic plant hormone in the auxin family or a plant growth regulator, which can find applications in tissue culture.1-Naphthaleneacetic acid (NAA) is a synthetic phytohormone auxin that is added to cell culture media such as Murashige & Skoog media and Chu′s N6 media.1-Naphthaleneacetic acid has been used:to modify MS media for the initiation of callusas a supplement in solid K3 medium for the selection of transformantsin the preparation of culture medium like V-KM medium and Cg medium
