Spectinomycin is an aminocyclitol antibiotic with a similar mechanism to aminoglycosides.
TOKU-E offers two forms of spectinomycin: spectinomycin DiHCl (S006) and spectinomycin sulfate (S016). In aqueous solution, spectinomycin DiHCl is freely soluble, and spectinomycin sulfate is sparingly soluble (0.150 mg/mL).
