EINECS:201-705-8
Purity:99%
Other Names:1-Naphthaleneacetic acid
1-naphthaleneacetic acid (NAA, also named 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.

Storage temperature: 5 – 30℃ in a cool and ventilated warehouse. Do not expose to temperatures above 35℃. Keep away from heat sources, sparks and open flames. Store in a dark place. High temperatures will accelerate the oxidation and color change of amines.
It must be completely sealed. Use coated iron drums / HDPE drums. Do not use ordinary carbon steel containers as amines will corrode the carbon steel and produce hydrogen gas. Do not leave it open. To prevent absorption of CO₂ and water vapor from the air, which will form carbonates and reduce catalytic activity.
Separate storage: Do not store together with strong acids, strong oxidants, or organic acids in the same warehouse. In the presence of strong acids, it will undergo intense neutralization and release heat. Avoid contact with copper and iron heavy metals.
Original factory sealed shelf life: 12 months. After opening, tighten the drum cover to isolate from air. It is recommended to use it within 6 months. After absorbing CO₂, the catalytic activity will decrease.
Q: What are the causes for the perforation of the foam, large-sized pores, and collapse of the bubbles?
A: Excessive addition of Bis(2-dimethylaminoethyl) Ether led to a rapid foaming reaction, causing gas to escape; reducing the amount of BDMAEE and using a gel-type amine catalyst simultaneously to balance the foaming-gelation reaction, and conducting a gradient test.
Q: What is the cause of the white crystals / white precipitates in the barrel?
A: The product absorbs CO₂ from the air, generating dimethylamino carbonate; this will reduce the catalytic activity; the appearance of precipitates is not recommended for feeding; storage must be strictly sealed to prevent contact with air.
Q: Can it be mixed directly with strong acids?
A: Direct and large-scale mixing is strictly prohibited; it will undergo intense neutralization and release heat; if pH adjustment is needed, it must be done at a low temperature, with a large amount of dilution, and slowly adding the strong acid while vigorously stirring.
Q: What is the minimum order quantity (MOQ)?
A: For industrial bulk goods, the regular MOQ is 25 kg; small samples can be provided for formula testing; small samples will charge a sample fee, and large order quantities can be negotiated to offset the sample fee.
