In doping control analysis, the characterization of urinary steroid metabolites is of high interest for a targeted and long-term detection of prohibited anabolic androgenic steroids (AAS). In this work, the structure of a long-term metabolite of dehydrochloromethyltestosterone (DHCMT) was elucidated. Altogether, eight possible metabolites with a 17α-methyl-17β-hydroxymethyl - structure were synthesized and compared to a major DHCMT long-term metabolite detected in reference urine excretion samples. The confirmed structure of the metabolite was 4α-chloro-18-nor-17β-hydroxymethyl-17α-methyl-5α-androst-13-en-3α-ol.
