What is 2-AMINO-5-PHENYL-1 3 4-THIADIAZOLE 96?

The Uses of 2-AMINO-5-PHENYL-1 3 4-THIADIAZOLE 96

2-Amino-5-phenyl-1,3,4-thiadiazole may be used for the synthesis of 1,3,4-thiadiazole derivatives.

General Description

2-Amino-5-phenyl-1,3,4-thiadiazole on condensation with benzaldehyde (SPT), 4-nitrobenzaldehyde (SNT), 4-methoxybenzaldehyde (SMT), 2-hydroxybenzaldehyde (SSTH) or 2-hydroxyacetophenone affords Schiff′s bases. Its molecular geometry and vibrational frequencies have been evaluated using the Hartree-Fock and density functional method (B3LYP). 2-Amino-5-phenyl-1,3,4-thiadiazole has been reported to inhibit the corrosion of mild steel in 0.5M H₂SO₄ and 1.0M HCl. Corrosion inhibition has been examined using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS).
