title: Colorimetric determination of stanozolol in pharmaceutical formulations.
abstract: In acidic medium, stanozolol reacts with phenoldisulfonic acid to form a stable yellow chromophore, which is quantitated by spectrophotometry at 385 nm. The reaction gives a linear response at concentrations from 5 to 50 micrograms/mL. The method is suitable for routine analytical control of stanozolol and its formulations.
