Quality Control of 2-Furoic hydrazide. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about Synthetic stratagem, characterization and biocidal applications of triorganotin(IV) complexes derived from hydrazide/hydrazone analogues.

A series of Schiff base ligands as benzylidene benzohydrazide and their hydrazone analogs (Ia-Ic) have been synthesized and then complexed with organotin(IV) moiety having general formula [R’3SnL] to get the target compounds (1-9), where L = C4H3OCONHN:CHR, R = C6H5O (Ia), C4H5O (Ib), C6H3Cl2 (Ic) and R’ = -CH3 (1-3), -CH2Ph (4-6), -Ph (7-9). They were fully characterized using FT-IR, NMR (1H, 13C and 119Sn) spectroscopy, along with elemental anal. and m.p. One of the precursor (Ib) has been analyzed by single crystal XRD to further authenticate the structure. The 119Sn NMR data suggest the mol. geometry of organotin derivatives as distorted pentagonal bipyramidal. They were also evaluated for their antibacterial, antifungal, α-amylase inhibition, DPPH, total reducing power and total antioxidant activities. Triaryltin(IV) derivatives show good antibacterial and antifungal activity. Whereas the data for antidiabetic activity demonstrated that the compounds may serve as moderately effective alpha amylase inhibitor.
