What is 2-Naphthoxyacetic Acid CAS 120-23-0?

2-Naphthoxyacetic Acid is a synthetic auxin-type plant growth regulator. It is supplied as a technical-grade active ingredient for agrochemical formulations and has the molecular formula C12H10O3.

Are BNOA and 2-NOA the same product?

Yes. BNOA, beta-naphthoxyacetic acid, and 2-NOA all refer to 2-Naphthoxyacetic Acid CAS 120-23-0. They should not be confused with 1-naphthoxyacetic acid or other naphthaleneacetic acid derivatives.

What crops and effects is 2-Naphthoxyacetic Acid used for?

It is used in plant growth regulator products for crops such as tomato, grape, strawberry, blackberry, and pineapple. Typical agronomic targets include improving fruit set, reducing premature fruit drop, and supporting fruit size and color development.

What specifications should be checked before ordering?

Confirm assay, appearance, melting range, water, residue on ignition, related impurities, and residual solvents. For this technical-grade material, also verify that the assay and physical form match the intended agrochemical formulation.

How should 2-Naphthoxyacetic Acid be stored and handled?

Store below 30 C in tightly closed containers in a cool, dry, well-ventilated area, away from strong oxidizers and incompatible materials. Use appropriate powder-handling controls to limit dust and direct skin or eye contact.

2-Naphthoxyacetic Acid CAS 120-23-0

2-Naphthoxyacetic Acid (CAS 120-23-0), chemically identified as (2-naphthalenyloxy)acetic acid, is a synthetic auxin functioning as a potent active ingredient in plant growth regulator formulation. This technical grade material, also extensively known in the agrochemical industry as BNOA or beta-naphthoxyacetic acid, is utilized to stimulate fruit set and prevent premature fruit drop in the commercial cultivation of tomatoes, strawberries, and blackberries.

Storage Conditions

To maintain product stability and activity, store 2-Naphthoxyacetic Acid under the following conditions:

Keep in tightly closed original containers.
Store in a cool, dry, well-ventilated warehouse, away from direct sunlight.
Recommended storage temperature: below 30 °C.
Protect from moisture, strong oxidizing agents and strong bases.
Avoid prolonged exposure to high temperature or strong light.

Safety Precautions

According to available safety data, 2-Naphthoxyacetic Acid is classified as harmful if swallowed and may cause skin and eye irritation and respiratory irritation.

Handling

Avoid formation and inhalation of dust.
Do not eat, drink or smoke while handling the material.
Use only in well-ventilated areas or with local exhaust.

Personal protection

Wear appropriate chemical-resistant gloves, long-sleeved protective clothing and safety shoes.
