Naphthalene Acetic Acid CAS 86-87-3

What Naphthalene Acetic Acid Is

Naphthalene acetic acid is a synthetic auxin, a man made plant growth regulator used for rooting and fruit set. It is a white to off-white crystalline technical powder that keeps at normal warehouse temperature with no cold chain. The free acid dissolves only slightly in cold water and is dissolved in alcohol or dilute alkali, while the sodium salt is water-soluble. UATChem supplies technical grade NAA for formulation, with assay and moisture on the lot COA.

Rooting, Fruit Set and Crop Uses

• Cutting rooting. Used in rooting dips and powders for woody and herbaceous cuttings to lift rooting rate and transplant survival, often blended with IBA.
• Fruit set and drop control. Applied on pome and stone fruit, tomato, grape, citrus and cotton to improve set and cut pre-harvest drop.
• Flower and fruit thinning. At higher use rates it thins flowers and young fruit on crops such as apple to balance load and improve fruit size.
• Tissue culture and formulation. A standard auxin in culture media for rooting and callus, and the technical active for rooting powders and soluble liquids.

Fruit set and crop development programs sometimes pair NAA with gibberellic acid, so UATChem also supplies gibberellic acid technical for the same PGR formulations.

Typical Specifications

Technical and tissue culture grades differ in assay and moisture, so content is not quoted as one fixed figure; assay, moisture and residue values are reported on the COA for each lot, and the physical constants below identify the material.

Packaging, Documents and Ordering

• Packed in 25 kg fiber drums and kraft bags, 1 kg foil sample packs and 1000 kg ton bags; store sealed in a cool, dry, ventilated place away from sunlight, strong alkali and oxidizers, with no refrigeration needed.
• NAA is a low toxicity plant growth regulator for labeled agricultural use; bulk handling uses goggles, dust mask and gloves with local extraction, and release to waterways is avoided. Each lot carries a COA with assay and moisture, plus TDS and SDS, and local PGR registration is handled by the buyer, with documents supported on request.
• For a quote, UATChem needs the grade (technical or tissue culture, free acid or sodium salt), quantity, packing and destination port.

FAQ

Q: What is naphthalene acetic acid used for?

A: It is a synthetic auxin used to root cuttings, set fruit, reduce pre-harvest drop, thin fruit and support tissue culture.

Q: How do I dissolve naphthalene acetic acid?

A: The free acid barely dissolves in cold water; predissolve in alcohol or dilute alkali, or use the water-soluble sodium salt.

Q: Is naphthalene acetic acid supplied as the technical active?

A: Yes, UATChem supplies NAA technical powder for rooting powders, liquids and sprays, with assay and moisture on each lot COA.
