| | NAPTALAM Usage And Synthesis |
| Chemical Properties | solid with an unpleasant odour | | Uses | N-(1-Naphthyl)phthalamic Acid is an auxin-transport inhibitor in plants resulting in the attenuation of root growth through decreasing the cell production rate. | | Uses | Selective preemergence herbicide used to control some grasses and many broadleaved
weeds in soybeans, cucurbits, asparagus, groundnuts, potatoes and established
woody ornamentals. | | Definition | ChEBI: A dicarboxylic acid monoamide which results from addition of one equivalent of 1-naphthylamine to phthalic anhydride. | | General Description | Naptalam is a purple crystalline solid, which can be used as an anti-geotropic agent and as an auxin (IAA) antagonist in plants. | | Agricultural Uses | Herbicide: Used as a selective pre-emergence herbicide to control
broadleaf weeds and grasses in soybeans, cucumbers,
melons, peanuts and woody ornamentals. Not currently
registered for use in the U.S. or EU countries. There are
25 global suppliers. | | Trade name | N-1-naphthyl-

®; NAPTRO®; NIP-A-THIN®; PEACH-THIN®;
RESCUE®[C]; 6Q8®; SOLO® | | Environmental Fate | Soil/Plant. Degrades in soils and plants forming 1-naphthylamine and phthalic acid
(Hartley and Kidd, 1987; Humburg et al., 1989). Residual activity in soil is limited to
approximately 3 to 4 months (Hartley and Kidd, 1987).
Chemical/Physical. Forms N-(1-naphthyl)phthalimide at elevated temperatures (Worthing
and Hance, 1991). Naptalam will precipitate as the free acid in very acidic waters
or in extremely hard waters (Humburg et al., 1989). | | Purification Methods | Crystallise the herbicide from EtOH (m 183-185o). The Na salt has m 185o. [Beilstein 12 H 1236, 12 I 525, 12 III 2876.] |
