The effect of 3-methyl 4-amino 1,2,4 triazole (MATA) on the corrosion behaviour of copper-nickel 70 - 30 (Monel) in NaCl 3 solution is investigated at K by weight loss measurements, potentiodynamic polarisation and impedance spectroscopy (EIS) methods.

Preliminary screening of the inhibition efficiency (ECR) was carried out with using weight- loss measurements. 3-Aminomercapto-1,2,4-triazole | C2H4N4S | CID - structure, chemical names, physical and chemical properties, classification, patents, literature.

The reaction of thiocarbohydrazide with carboxylic acids at the melting temperature allows an improved preparation of the S-substituted 4-aminomercapto-1,2,4-triazole heterocycles. The crude 4-aminomercapto-1,2,4-triazoles react easily with carboxylic acids or carboxylic acid chlorides to afford the 1,2,4-triazolo[3,4-fc][1,3,4.

Phenotypic high content screening against the intracellular parasite in infected VERO cells was used to identify a novel hit series of 5-amino-1,2,3-triazolecarboxamides (ATC). Optimization of the ATC series gave improvements in potency, aqueous solubility, and metabolic stability, which combined to give significant improvements in oral.
