General description

Desmethyldoxpein is the primary urinary metabolite of doxepin, a tricyclic antidepressant used for the treatment of sleep maintenance and sold under trade names such as Silenor® and Aponal. This analytical reference standard is suited for use in LC/MS or GC/MS methods for urine drug testing, clinical toxicology, and forensic analysis applications.

Application

Desmethyldoxepin solution may be used as an internal standard in the high performance liquid chromatographic (HPLC) determination of bupivacaine in samples of human serum.
