The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2-(7-Bromo-1H-indol-3-yl)acetic acid(SMILESS: O=C(O)CC1=CNC2=C1C=CC=C2Br,cas:63352-97-6) is researched.Quality Control of Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate. The article 《Response of substituted indoleacetic acids in the indolo-α-pyrone fluorescence determination》 in relation to this compound, is published in Physiologia Plantarum. Let’s take a look at the latest research on this compound (cas:63352-97-6).
The fluorescence determination of IAA (using the fluorescence of its α-pyrone derivative) was investigated to study possible interference from 4-chloro-IAA and 5-hydroxy-IAA, which occur naturally. Both compounds showed ∼40% of the fluorescence of IAA after conversion to their α-pyrones. Halogenated IAA showed 0-60% of the fluorescence of IAA. Thus, concentration of IAA cannot be determined in crude extracts in the presence of 4-chloro- or 5-hydroxy-IAA because sep. determinations of each of these compounds are not possible by changing the excitation or fluorescence wave-lengths of the testing equipment.
In addition to the literature in the link below, there is a lot of literature about this compound(2-(7-Bromo-1H-indol-3-yl)acetic acid)Electric Literature of C10H8BrNO2, illustrating the importance and wide applicability of this compound(63352-97-6).
