High Purity 1-Naphthaleneacetic Acid (NAA) 98% TC | Premium Plant Growth Regulator (CAS No.: 86-87-3)
What is 1-Naphthaleneacetic Acid (NAA)?
1-Naphthaleneacetic acid (NAA), with CAS No. 86-87-3, is a potent synthetic phytohormone belonging to the auxin family. Unlike natural auxins, NAA remains stable inside plants for a longer duration, providing sustained growth stimulation. It acts as a vital ingredient in commercial rooting powders, fruit-thinning agents, and anti-dropping sprays.

Key Applications & Benefits in Agriculture
-
Superior Rooting Agent: NAA significantly accelerates the formation of adventitious roots in plant cuttings, making it a staple for nurseries and tissue culture laboratories.
-
Prevents Pre-Harvest Fruit Drop: Spraying NAA on apples, pears, citrus, and cotton before harvest effectively prevents premature abscission (fruit/pod drop), securing your harvest yield.
-
Blossom and Fruit Thinning: At specific concentrations, NAA acts as an effective thinning agent for fruit trees, helping balance fruit load and improve the final size and quality of the remaining produce.
-
Promotes Flowering & Fruit Set: It stimulates flowering in pineapples, increases fruit-setting rates in tomatoes and peppers, and enhances the plant's resistance to environmental stress.

Recommended Dosage & Usage Guide
Note: The effect of NAA heavily depends on the concentration and the specific crop stage. Always conduct a small-scale test before wide application.
-
For Rooting Cuttings: Dip the base of cuttings in a 100–500 ppm solution or mix into rooting powder bases.
-
To Prevent Fruit Drop: Spray at 10–20 ppm during the mid-to-late growth stage or 2-3 weeks before harvest.
-
For Fruit Thinning: Apply at 5–30 ppm depending on the fruit tree species (e.g., apples or pears) shortly after full bloom.
Handling, Storage & Packaging
-
Safety & Handling: Wear personal protective equipment (gloves, goggles). Avoid inhaling dust or direct skin contact.
-
Storage Conditions: Store in a cool, dry, and well-ventilated warehouse. Keep the container tightly sealed and away from direct sunlight, moisture, and incompatible alkaline materials.
-
Available Packaging: 1 kg/aluminum foil bag, 25 kg/fiber drum, or customized packaging based on bulk wholesale requirements.
Q1: Is NAA soluble in water?
A1: Pure NAA (98% TC) has low solubility in cold water. To dissolve it completely, it is recommended to first dissolve the powder in a small amount of ethanol, acetone, or an alkaline solution (like diluted sodium hydroxide), and then dilute it with water to the required concentration. Alternatively, you can look into its water-soluble salt form, NAA-Na (Sodium 1-naphthaleneacetate).
Q2: What is the difference between NAA and IBA?
A2: While both are auxin-type plant hormones used for rooting, IBA (Indole-3-butyric acid) is generally better for initiating root branching and root hair development, while NAA is excellent for inducing the initial adventitious root formation and is often more cost-effective for broad agricultural use. They are frequently combined for optimal results.
