Organic & Medicinal Chem IJ. ; 3(2): DOI: /OMCIJ – To evaluate the effect of some tetrazole compounds as corrosion inhibitors of copper in HNO3 at various temperatures., – 1‐phenyl‐5‐mercapto‐1,2,3,4‐tetrazole (PMT) was selected as the best inhibitor among the tetrazole compounds tested.
Gravimetric and electrochemical techniques were conducted., – PMT was an excellent inhibitor for copper in by: Tetrazoles with an aldehyde group at the 5-position have recently been prepared as outlined in Scheme The 1-substituted tetrazolecarbaldehydes () were more reactive than the corresponding 2-substituted formed hydrates such as () and hemiacetal dimers ().The aldehyde groups showed the range of normal aldehyde reactions for both 1- and 2-substituted tetrazole Search results for tetrazolium chloride at Sigma-Aldrich.

The produced chitosan was characterized with deacetylation degree of %, a molecular weight of × 10 4 Da, and % solubility in 1% acetic acid solution.
The antibacterial activity of fungal chitosan was evaluated against two foodborne pathogens, that is, Salmonella typhimurium and Staphylococcus aureus, using. One of the main procedures frequently used for the preparation of 5-substituted tetrazoles 7 involves heating a suspension of 6, sodium azide, ammonium chloride and lithium chloride ( g, 28 mmol) in anhydrous dimethylformamide (DMF) under stirring at °C [15,16,17].
