4,5,6,7-Tetrahydro-7-oxobenzo[b]thien-4-ylurea; Sulbenox1, a novel animal growth stimulant

The title compound, a metabolite of 4,5,6,7-tetrahydrobenzo[b]thien-4-ylurea, was synthesized and found to be an effective growth promoter in sheep, mice, and rats. In sheep it gave over a 6-week growth period at 15 and 60 ppm in the diet an economically and statistically significant growth response.
