Molecular requirements for auxin activity. I. Halogenated indoles and indoleacetic acid was written by Porter, William L.;Thimann, Kenneth V.. And the article was included in Phytochemistry (Elsevier) in 1965.Related Products of 1912-45-4 This article mentions the following:
2-Chloroindoleacetic acid had 350% of the activity of indoleacetic acid (IAA) in the pea curvature test; the 2-bromo analog had 160% activity and the corresponding Me and Et esters were even more active. In a series of these and other IAA derivatives, the log of the growth activity is a linear function of the NH stretching frequency in the ir spectra and of the Hammett sigma value for the substituent. In the experiment, the researchers used many compounds, for example, 2-(5-Chloro-1H-indol-3-yl)acetic acid (cas: 1912-45-4Related Products of 1912-45-4).
2-(5-Chloro-1H-indol-3-yl)acetic acid (cas: 1912-45-4) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Related Products of 1912-45-4
