The aim of this work is to detect how 3,5-diacetamido-2,4,6-triiodosodium benzoate (sodium amidotrizoate), a synthetic derivative of the anti-auxin triiodonezoic acid (TIBA), influences the growth and content of primary metabolites in the green alga <italic>Chlorella vulgaris</italic> Beijerinck. It strongly suppressed cell number by 6-20%, chlorophyll <italic>a</italic> by 6-14%, chlorophyll <italic>b</italic> by 20-24%, total carotenoids by 7-13% and monosaccharides by 7-8% at the concentration of 10-4 M, in comparison to the control. On the other hand, sodium amidotrizoate applied at lower concentrations (10-7 - 10-6 M) acted as a weak stimulator of analyzed biochemical compounds in algal cells. No statistically significant effect was detected with the application of sodium amidotrizoate at a concentration of 10-8 M. It seems that sodium amidotrizoate plays an important role in algal growth and development and probably possesses anti-auxin activity, like TIBA.
