Description
STANDARDISED BOTANICAL ACTIVE
Yohimbine Hydrochloride — 98.0%
Yohimbine hydrochloride is the hydrochloride salt of the Pausinystalia johimbe bark alkaloid, supplied at 98.0% by HPLC. Buyers should state the salt form at enquiry stage: the free base and the hydrochloride differ in molecular weight, so a specification written in free-base terms will not match a hydrochloride COA.

Buyer Decision Guide
The two recurring mismatches on this material are salt form and reference basis. Both are resolved on paper before the first order, not in the warehouse.
- Assay: 98.0% by HPLC, expressed on the hydrochloride salt.
- Salt form stated explicitly on the COA so free-base comparisons can be converted.
- Identity confirmed against a yohimbine reference standard.
- Related Pausinystalia alkaloids limited in the agreed specification.
- Loss on drying, heavy metals and microbiology reported per batch.
- COA, specification sheet and safety data sheet accompany each shipment.
How This Grade Differs
Yohimbine free base and yohimbine hydrochloride are not interchangeable on a weight basis. This grade is the hydrochloride; if your specification is written as free base, the assay and the quantity both need converting before comparison.
Quality and Documentation
Assay is run against a yohimbine reference standard, with the salt form recorded on the batch file. Related alkaloids, residual solvents, loss on drying and heavy metals are reported per lot.
Regulatory Note
This material is supplied as a reference and industrial raw material. It is not offered as a food, dietary supplement or finished pharmaceutical product. Regulatory status, permitted uses, import licensing and labelling are the buyer’s responsibility for the destination market.
