C35H49NO10 (643.3356294)

Buprenorphine glucuronide is a metabolite of buprenorphine. Buprenorphine is a semi-synthetic opioid that is used to treat opioid addiction in higher dosages (>2 mg), to control moderate acute pain in non-opioid-tolerant individuals in lower dosages, and to control moderate chronic pain in dosages ranging from 20–70 µg/hour.
