Greentree Chemical Co., Limited is one of the leading manufacturers and suppliers of 1-naphthylacetic acid/naa 98%tc cas no. 86-87-3 plant growth regulator in China. With abundant experience, our factory offer high quality chemicals made in China with competitive price. Welcome to contact us for free sample.
Naphthylacetic Acid (NAA) is a synthetic plant growth regulator widely used in agriculture to enhance root development, improve fruit setting, and boost crop yields. Functioning similarly to natural auxins, NAA promotes cell elongation and division, making it invaluable for plant propagation and tissue culture.
| Specification | 98%TC |
| Chemical Name | Naphthylacetic acid; 1-Naphaleneacetic acid NAA; Naphthyl acetic acid; NAA Plant hormone |
| Appearance | White powder |
| Molecular Formula | C12H10O2 |
| Molecular Weight | 186.2 |
| Melting Point | 134-135°C |
| Solubility | Water solubility 420mg/L (20ºC); organic solvent solubility (g/L.26ºC) xylene 55; easily soluble in alcohol; soluble in ether; alkali metal salts and ammonium salts are easily soluble in water. |
| Stability | Under the condition of pH value of 3-6, naphthaleneacetic acid shows good stability, but it is easy to decompose under strong acid or strong base conditions. In addition, naphthaleneacetic acid also shows certain stability to light and heat, but under acidic conditions, sodium naphthaleneacetate will exist in the form of acid, which may affect its chemical properties and stability. |

Products Features
1. Naphthaleneacetic acid is a powerful plant growth regulator that promotes plant growth and development.
2. Naphthaleneacetic acid can regulate plant growth and development through absorption and transport in plant tissues such as roots, stems and leaves.
3. The mechanism of action of naphthylacetic acid is to affect the growth and development of plants by regulating the synthesis and metabolism of plant hormones.
Products Applications
1. Rooting Agent: NAA is widely used to stimulate root growth in cuttings, making it essential for plant propagation and nursery practices.
2. Fruit Setting: It enhances fruit setting by preventing flower and fruit drop, improving yield in crops like tomatoes and apples.
3. Seedless Fruit Production: NAA induces parthenocarpy, enabling the development of seedless fruits such as grapes and cucumbers.
4. Tissue Culture: It promotes cell division and elongation, making it a key component in plant tissue culture media.
5. Pre-Harvest Management: NAA reduces pre-harvest fruit drop, ensuring higher-quality yields in orchards.
6. Vegetative Growth: It encourages lateral bud development and overall plant vigor, beneficial for ornamental and horticultural plants.
7. Stress Resistance: NAA helps plants withstand environmental stresses, such as drought or salinity, by improving root systems.
8. Agricultural Efficiency: Its use in low concentrations makes it a cost-effective solution for enhancing crop productivity and quality.
Precautions
1. Dosage control: When using naphthaleneacetic acid, pay attention to the dosage control to avoid excessive use, which may cause abnormal plant growth or negative effects.
2. Timing of use: The timing of naphthaleneacetic acid should be determined according to different plants and application purposes. Choose the appropriate growth stage for fertilization to achieve the best results.
3. Storage and safety: Naphthaleneacetic acid should be stored in a dry, cool place, away from fire and children. Pay attention to safety during use and avoid contact with skin and eyes.
