Safety of 2-(Bromomethyl)pyridine hydrobromideIn 2017 ,《Pyridine-antipyrine appended indole derivative for selective recognition of Fe3+: Concentration dependent coloration》 appeared in Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy. The author of the article were Ta, Sabyasachi; Nandi, Sandip; Ghosh, Milan; Banerjee, Somenath; Das, Debasis. The article conveys some information:
Combination of pyridine, antipyrine and indole in a single mol. (L2) allows selective recognition of Fe3 + colorimetrically in CH3CN. The structure of L2 is confirmed from single crystal x-ray diffraction anal. The probe displays two different visible bands at 541 nm and 715 nm in the presence of Fe3 +, associated with two different colors, viz. green and pink-violet allowing determination of unknown Fe3 + concentration Removal of 2-picolyl group from indole N-center of L2 generates L3 that behaves similarly at low Fe3 + concentration (> 0 to 1.1 mM) but differently at higher Fe3 + concentration (> 1.1 mM), indicating involvement of pyridyl-N donor towards Fe3 +, and hence different coordination environment around Fe3 + at higher concentration In the experiment, the researchers used 2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8Safety of 2-(Bromomethyl)pyridine hydrobromide)
2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.Safety of 2-(Bromomethyl)pyridine hydrobromide
