Usage

Description

(4-Methoxyphenyl)arsonic acid, also known as Methylarsonic acid, is a chemical compound with the formula C7H9AsO4. It is a derivative of arsenic and is commonly used in the agricultural industry.
Used in Agricultural Industry:
(4-Methoxyphenyl)arsonic acid is used as a pesticide and herbicide for controlling the growth of unwanted plants. It works by inhibiting the enzyme glutamine synthetase, which is essential for plant growth.
However, it is important to note that (4-Methoxyphenyl)arsonic acid is considered toxic and must be handled with caution. Studies have shown that it can accumulate in the environment and pose risks to human health through food and water contamination. Therefore, it is crucial to use this compound responsibly and carefully to minimize its potential negative impacts.

Substituted phenylarsonic acids; structures and spectroscopy

Full NMR and ESI-MS spectra, and differential scanning calorimeter data are presented for 15 substituted phenylarsonic acids, including two new fluoro-substituted examples. X-ray crystal structure determinations of five examples (phenylarsonic acid and the 4-fluoro-, 4-fluoro-3-nitro-, 3-amino-4-hydroxy- and 3-amino-4-methoxy-substituted derivatives) were determined and the H-bonding crystal-packing patterns analysed.

SYNTHESIS AND PROPERTIES OF ARYLARSONIC ACIDS

1.A number of arylarsonic acids with various substituents in the ortho, meta, and para positions in the benzene ring were synthesized from diazonium salts by the Bart reaction; the products were characterized by their IR spectra. 2.By the DTA method it was established that arylarsonic acid molecules were linked together through hydrogen bonds to form oligomeric associated forms. 3.The IR spectra of arylarsonic acids confirm the presence in them of strong hydrogen bonds through which they are able to undergo association into two forms differing in the symmetry of the d isposition of the As=O bonds.A form which gives a C band arises if the arsonyl oxygen participates in the formation of two hydrogen bonds simultaneously, as a result of which the molecules are linked together to form endless chains and columns.In the other form there are probably cyclic dimers with intermolecular H bonds.
