Uses

Boldenone Undecylenate is an anabolic steroid developed for veterinary use.

Manufacturing Process

To a solution 5 g of L-dehydrotestosterone in 25 ml of benzene was added 3 ml of pyridine and 7.1 ml undecylene chloride.
The mixture was heated for 2 heurs at 70°C.
After cooling pyridine hydrochloride was filtered off.
The filtrat was purified via chromatography on neutral aluminum oxide. Benzenic eluate was concentrated to obtain 1-dehydrotestosteron 17-undecylenate (boldenone undecylenate) as an oil; λmax 243-244 nm.
