The closeness of fit of antibenzoate antibodies about haptens and the orientation of the haptens in combination was written by Pressman, David;Siegel, Malcolm;Hall, Luther A. R.. And the article was included in Journal of the American Chemical Society in 1954.Related Products of 5344-49-0 This article mentions the following:
The inhibitory action of chloro-substituted phenylazobenzoates on the specific precipitation of antibodies formed against benzoate ions yielded information about the closeness of fit about hapten of the previously uninvestigated portion of the antibody complementary region. With antibodies to the o-azobenzoate ion, the fit about the benzene ring was closest in the 3- and 4-positions and least close in the 6-position. With antibodies to m-benzoate, the fit was closest in the 4-position, least close in the 5-position, and intermediate in the 2- and 6-positions. For those cases where 2 orientations for the combination of hapten with antibody are possible, such as with the chlorobenzoates, the relative distribution was calculated For example, m-chlorobenzoate, which has been considered to combine with anti-m-azobenzoate antibodies with the Cl in the azospecific site of the antibody, is calculated to combine to the extent of 10% in the nonpreferred orientation. The following substituted benzoic acids (R = p-hydroxyphenylazo) were prepared, m.ps. are given: 3,2-Cl, R, 187-9°; 4,2-Cl, R, 245-6°; 5,2-Cl, R, 231-3°; 6,2-Cl, R, 194-5°; 2,3-Cl, R, 219-21°; 4,3-Cl, R, 268-71°; 5,3-Cl, R, 239-41°; 6,3-Cl, R, 244-6°; 2,4-Cl, R, 213-15°; o-R, 207.8-8.2°; m-R, 230-2°; p-R, 277-9° (decomposition). In the experiment, the researchers used many compounds, for example, 2-Chloro-6-nitrobenzoic acid (cas: 5344-49-0Related Products of 5344-49-0).
2-Chloro-6-nitrobenzoic acid (cas: 5344-49-0) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Related Products of 5344-49-0
