Naphthalene Acetic Acid (NAA) 
Naphthalene Acetamide (NAD) 
After single oral doses of naphthaleneacetate in rats, four metabo- 
lites were found in the urine. Two were identified as naphthaceturic acid 
and naphthacetylglucosiduronic acid. A third compound was apparently as a 
sulfate, indicating possible hydroxylation. The fourth was unidentified 
(1695). Hydrolysis of the methyl ester of naphthaleneacetic acid was ob- 
served during storage of treated potatoes (1546). 
When Winesap and Stayman cultivars were exposed to NAA or NAD, some 
decarboxylation occurred and six conjugates were formed. Pea roots exposed 
to NAA produced NAA-aspartate (1548). 
Exposure of NAA to ultraviolet light and sunlight produced 1-hydroxy- 
methyl naphthalene, l-naphthaldehyde, naphthalene-l-carboxylic acid and 
l-methyl naphthalene under aerobic conditions. Anaerobically, only the l- 
methyl analog was observed (1391) phthalic acid‘has also been observed (1791). 
When NAA was incubated with Aspergillus niger , the major metabolite 
was found to be the 5-hydroxy analog. The 4- and 6-hydroxy analogs were 
also observed(1731). 
Nellite [ Phenyl-N,N'-dimethylphosphorodiamidate] 
Metabolism studies were carried out with l-month-old soil grown 
cucumber plants (Cucumis sativus). When pheny1-1-!4c-1abeled Nellite was 
used, phenol was isolated and identified. Hydrogen phenyl methylphosphor- 
amidate and dihydrogen phenyl phosphate were provisionally identified in 
the same fraction. From another fraction, which contained lipophilic 
materials, phenol and dihydrogen phenyl phosphate were obtained after 
alkaline hydrolysis (969, 1740).
