Tetrazoles and their derivatives are insensitive energetic molecules that can be used in the compounding of the high energy material. Herein, two types of bis hyroxyethyl tetrazole compounds have been synthesized using bisnitrile and sodium azide and via consequent alkylation of the reaction product .The structure of all products have been confirmed by 1HNMR, MASS spectroscopy and elemental analysis. Also, for better interpretation of the 1HNMR spectra of bishydroxy ethyl tetrazole, the most stable conformation of 2-(5-methyl-2H-tetrazol-2-yl)ethan-1-ol (as a model molecule) have been investigated. The results of conformational analysis have indicated that the most stable conformation is gouch one. So, under basis of the 1HNMR and conformational analysis, the presence of an intramolecular hydrogen bond between –OH group and the 2-N atom of tetrazole ring in hydroxyl ethyl tetrazole componds was confirmed.
