2163-77-1 Usage
General Description
3-amino-4-hydroxyphenylarsonic acid, also known as p-arsanilic acid, is a chemical compound that is used as a feed additive in the poultry industry to promote growth and prevent disease. It is derived from the arsenic compound arsanilic acid, and is known to have antimicrobial properties. However, its use has raised concerns about the potential for arsenic residues to accumulate in poultry meat and eggs, leading to health risks for consumers. As a result, there have been efforts to regulate and limit the use of p-arsanilic acid in food production. Additionally, the compound has been studied for its potential environmental impact, as it can leach into soil and water systems, contributing to arsenic contamination.
Check Digit Verification of cas no
The CAS Registry Mumber 2163-77-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2163-77:
(6*2)+(5*1)+(4*6)+(3*3)+(2*7)+(1*7)=71
71 % 10 = 1
So 2163-77-1 is a valid CAS Registry Number.

Substituted phenylarsonic acids; structures and spectroscopy
Lloyd, Nicholas C.,Morgan, Hugh W.,Nicholson, Brian K.,Ronimus, Ron S.
, p. 2443 - 2450 (2008/09/20)
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.
