説明
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.
化学的特性
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.
主な応用
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.
使用
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
製造方法
Industrially, 1-naphthaleneacetic acid is prepared by condensation reaction of naphthalene and chloroacetic acid in the presence of catalyst potassium chloride or aluminum powder.
定義
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.
一般的な説明
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.
危険性
Skin irritant.

輸送方法
UN1759 Corrosive solids, n.o.s., Hazard Class:
8; Labels: 8-Corrosive material, Technical Name Required.
純化方法
Crystallise the acid from EtOH or water. [Beilstein 9 H 666, 9 IV 2424.]
不和合性
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).
廃棄物の処理
Incineration. In accordance
with 40CFR165, follow recommendations for the disposal
of pesticides and pesticide containers.
