1-Naphthaleneacetic acid Chemical Properties,Usage,Production

Description

1-naphthaleneacetic acid (NAA), also known as α-naphthaleneacetic acid, belongs to a class of organic compounds of naphthalenes, which contain a naphthalene moiety of two fused benzene rings. NAA is a synthetic auxin plant hormone. It is used as a plant growth regulator to control preharvest fruit drop, flower induction and fruit thinning in various crops such as apples, potatoes, olives, and citrus fruits. It is used as a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture and as herbicide. Applied as a dust or spray it delays dissolution of the abscission layer, retarding the fruit drop. The effect of NAA on plant growth is greatly dependent on the time of admission and concentration. When used after four weeks, NAA stimulates shoot growth, while full-time use limits growth. When used in a 4-week pulse, adventitious root growth is greatly increased.

Chemical Properties

White needle crystal or crystalline powder, odorless. Slightly soluble in cold water and ethanol, easily soluble in hot water, acetone, ether, chloroform, benzene, acetic acid and alkali solution.

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.  Inducing rooting of plant cuttings, spraying apple trees to prevent early drop, fruit thinner.
1-Naphthaleneacetic acid has been used:
to modify MS media for the initiation of callus
as a supplement in solid K3 medium for the selection of transformants
in the preparation of culture medium like V-KM medium and Cg medium

Application

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.

Preparation

Industrially, 1-naphthaleneacetic acid is prepared by condensation reaction of naphthalene and chloroacetic acid in the presence of catalyst potassium chloride or aluminum powder.

Definition

ChEBI: 1-naphthaleneacetic acid is a naphthylacetic acid substituted by a carboxymethyl group at position 1. It has a role as a synthetic auxin. It is a conjugate acid of a 1-naphthaleneacetate.

General Description

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. It is used for the vegetative propagation of plants from stem and leaf cutting, abscission promoter and substrate for auxin inducers of specific plant enzymes. Further, it stimulates root formation in cuttings of woody and herbaceous plants. It is also used to prevent premature flower and fruit drop. It is also employed to control regrowth of tree sprouts after trimminguse. In addition to this, it is used in ornaments and serves as an ingredient in many commercial plant rooting horticultural products.

Hazard

Skin irritant.

Agricultural Uses

Plant growth regulator: An agent 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 (pending). Registered for use in the U.S. and Canada.

Biochem/physiol Actions

1-Naphthaleneacetic acid is one of the synthetic auxins, used in plant propagation. It can induce the formation of lateral and adventitious roots.

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.
