This colourless solid is soluble in organic solvents. It features a carboxylmethyl group (CH<sub>2</sub>CO<sub>2</sub>H) linked to the "1-position" of [[naphthalene]]. NAA is a [[plant hormone]] in the [[auxin]] family and is an ingredient in many commercial [[rooting|plant rooting]] [[horticultural]] products; it is a rooting agent and used for the [[vegetative propagation]] of plants from stem and leaf cutting. It is also used for plant [[tissue culture]].<ref>[http://www.patentstorm.us/patents/6800482-description.html Cultured cells of Australian laurel, Pittosporaceae and a method for culturing tissues by using said cultured cells US Patent Issued on October 5, 2004]</ref> ==See also== *[[Auxin]] *[[Micropropagation]] *[[Tissue culture]] *[[SUPERthrive]] ==References== {{Reflist}} ==External links== * [http://www.sciencelab.com/xMSDS-1_Naphthaleneacetic_acid-9926176 MSDS] *[http://books.google.com/books?id=Jh_LiAVmSNQC&pg=PA503&lpg=PA503&dq=%22Naphthaleneacetic+acid%22+%22first+synthesized%22&source=web&ots=wcBbngn8ot&sig=5MowEDBHklmlW5fWLfOZxUy-9KQ#PPA133,M1 Handbook of Plant Physiology] {{DEFAULTSORT:Naphthaleneacetic acid, 1-}} [[Category:Auxins]] [[Category:Aromatic acids]] [[Category:Naphthalenes]] {{organic-compound-stub}} [[de:1-Naphthylessigsäure]] [[it:Acido 1-naftilacetico]] [[pl:Kwas naftylooctowy]]
