Previous studies have identified that indole-oxidases are present in P. putida, whose major ligands are heterocyclic substrates and have an interesting affinity when the substrate is indole. 19005-93-7, formula is C9H7NO, Name is 1H-Indole-2-carbaldehyde. These enzymes oxidize the ring so the substrate turns into Indigo. COA of Formula: C9H7NO.
Singh, Archana;Nishith, U.;Trivedi, Darshak R. research published 《 Spectroscopic studies of colorimetric receptors for detection of biologically important inorganic F–, AcO– and H2PO–4 anions in organo-aqueous medium: Real-life application》, the research content is summarized as follows. Two new 4-nitrobenzylidene based receptors 2-((E)-(((E)-4-nitrobenzylidene) hydrazono) methyl)-1H-indole, I, and 2-((E)-(((E)-4-nitrobenzylidene)hydrazono)methyl)-1H-pyrrole, II, have been designed and synthesized by the simple condensation reaction and characterized by using spectroscopic techniques. The receptors exhibited high sensitivity and selectivity towards biol. important anions such as F–, AcO– and H2PO–4 in DMSO and sodium salts F–, AcO– and H2PO–4 in aqueous medium (9:1 volume/volume, DMSO: H2O). The receptors I and II dispensed high sensitivity towards sodium arsenite and detection limit were found to be 0.143 ppm and 0.32 ppm in (9:1 volume/volume, DMSO: H2O) reflect the stable complex formation of the receptor with AsO–2 ion in aqueous medium. 1H NMR titration carried out to understand the nature of interaction between receptor I and F– ion. Cyclic voltammetric studies performed for receptors I and II in DMSO exhibited shift in oxidation and reduction peak with addition of basic F– ion signifying strong interaction between receptors and anions. Interesting, receptor I exhibited high selectivity for AcO– ion in the different range of pH from (6-11). Furthermore, receptor I and II showed colorimetric sensing of F– and AcO– ion present in com. available toothpaste and vinegar in the form of Na+F– and Na+AcO– in aqueous medium.
