Overview
Yohimbine is a naturally occurring alkaloid extracted from the bark of the Pausinystalia yohimbe tree, native to Central and West Africa. It has been traditionally used in folk medicine and modern pharmaceuticals due to its stimulant and vasodilatory effects. The compound is classified as an alpha-2 adrenergic receptor antagonist, which influences neurotransmitter release and blood flow. In B2B markets, yohimbine is primarily supplied as a bulk chemical for pharmaceutical formulations, research applications, and dietary supplements. Its demand is driven by studies exploring its potential in treating erectile dysfunction, obesity, and cognitive enhancement, though regulatory approvals vary by region.
Physical and Chemical Properties
Yohimbine is a white to off-white crystalline powder with a molecular weight of 354.44 g/mol. It melts at 235-236 °C and is soluble in organic solvents like ethanol and methanol, though only slightly soluble in water. The compound’s stability is best maintained in dry, cool environments protected from light. Its chemical structure includes an indole alkaloid core, which contributes to its biological activity. As an alpha-2 adrenergic antagonist, yohimbine inhibits receptors that regulate norepinephrine release, leading to increased sympathetic nervous system activity. This mechanism underpins its stimulant and vasodilatory effects.
Main Applications
Yohimbine’s primary use is in pharmaceuticals, where it is formulated into drugs for erectile dysfunction and hypotension. It is also studied for its potential in fat loss supplements due to its ability to promote lipolysis. Research applications include neuroscience investigations into adrenergic receptor functions. In the dietary supplement industry, yohimbine is marketed for its purported energy-boosting and performance-enhancing effects. However, regulatory scrutiny varies; for example, the FDA approves its use in prescription medications but restricts its inclusion in over-the-counter supplements without specific claims.
Safety and Storage
Yohimbine requires careful handling due to its potent pharmacological effects. Overdose or misuse can lead to hypertension, tachycardia, anxiety, and gastrointestinal distress. Proper personal protective equipment (PPE) such as gloves and masks is recommended during laboratory handling. Storage should be in airtight containers, away from moisture and light, at temperatures below 25 °C. Bulk procurement should include certificates of analysis (COA) to verify purity and composition, as impurities can amplify adverse effects.
B2B Procurement Guide
B2B buyers should prioritize suppliers with pharmaceutical-grade certifications (e.g., USP, EP) for purity assurance. Key procurement considerations include batch consistency, regulatory compliance (e.g., FDA, EMA), and scalability. Prices vary by purity (typically 98%-99.5%) and order volume, with bulk discounts available for research or industrial use. Due to its dual-use potential (pharmaceutical vs. research), buyers must clarify end-use to ensure compliance with local regulations. Reliable suppliers provide detailed SDS and COA documentation, and some offer custom synthesis for derivative compounds.
