The molecule is an organophosphate oxoanion that is the conjugate base of dihydrostreptomycin 3'alpha,6-bisphosphate arising from deprotonation of the phosphate OH groups and protonation of the guanidino and secondary amino groups; major species at pH 7.3. It is a conjugate base of a dihydrostreptomycin 3'alpha,6-bisphosphate.
