Alpha Yohimbine

Alpha-yohimbine, also known as rauwolscine, is an indole alkaloid and a stereoisomer of yohimbine, supplied by Nustras as a high-purity material for pharmaceutical and research applications. It occurs in Rauvolfia and Pausinystalia johimbe species and acts as a potent alpha-2 adrenergic receptor antagonist. It is a distinct compound from yohimbine hydrochloride, which Nustras lists separately.

The material is used by licensed pharmaceutical manufacturers and research laboratories as a reference standard and research chemical. It is not a dietary-supplement or food ingredient; it is supplied only to qualified, licensed buyers for lawful use, with no therapeutic or performance claims made.

The common name is rauwolscine or alpha-yohimbine, carrying CAS 131-03-3 for the free base, with the hydrochloride salt supplied where specified. It is a white to off-white crystalline powder; purity and assay are determined by HPLC to specification and confirmed on each lot's certificate of analysis. The related compound yohimbine hydrochloride is available on a separate page.

Nustras supplies alpha-yohimbine in documented pack sizes against a signed specification and the appropriate licensing, with a certificate of analysis and safety data sheet on every lot, to qualified buyers internationally subject to applicable controls. Yohimbine and its stereoisomers are prescription or restricted substances in many jurisdictions and are not permitted as isolated ingredients in natural health products; Nustras supplies this material only to buyers holding the appropriate licences, for lawful pharmaceutical or research use.
