Overview
Asarone, specifically α-Asarone, is a phenylpropene derivative primarily extracted from plants of the Acorus genus, such as Acorus calamus. It is a key aromatic compound with a sweet, spicy odor, historically used in traditional medicine and perfumery. Industrially, it serves as a flavoring agent and intermediate in organic synthesis. Research highlights its bioactivity, including potential sedative and insecticidal effects, though regulatory restrictions apply in some regions due to toxicity concerns. B2B buyers should prioritize suppliers adhering to quality standards for pharmaceutical or cosmetic-grade applications.
Physical and Chemical Properties
α-Asarone is a viscous liquid at room temperature with a molecular weight of 208.25 g/mol. Its density of 1.09 g/cm³ and boiling point near 297°C reflect moderate volatility. The compound is lipophilic, dissolving readily in ethanol and ether but not in water, which influences its formulation in industrial applications. Its stability is compromised by prolonged exposure to light or air, necessitating amber glass containers or nitrogen-filled packaging for storage. Analytical methods like GC-MS or HPLC are recommended for purity verification, typically ≥95% for commercial use.
Main Applications
In the fragrance industry, α-Asarone imparts earthy notes to perfumes and soaps. It also features in traditional Ayurvedic and Chinese medicine for its purported neuroprotective properties, though clinical evidence remains limited. Modern research explores its role as a natural insect repellent and antimicrobial agent. Industrial uses extend to synthetic intermediates for pharmaceuticals, where its methoxy and propenyl groups enable further chemical modifications. Buyers should confirm regulatory compliance (e.g., IFRA, FDA) for target markets, as restrictions apply in food or drug formulations.
Safety and Storage
α-Asarone requires careful handling due to potential neurotoxicity and skin irritation. Safety data sheets (SDS) recommend gloves, goggles, and fume hoods during processing. Storage must avoid heat and humidity; inert gas blankets can prevent oxidation. Regulatory agencies like the FDA limit its use in consumables, while the EPA evaluates its environmental impact. Disposal should follow hazardous waste protocols. Bulk purchases demand certified COAs (Certificates of Analysis) to ensure traceability and purity.
B2B Procurement Guide
Procuring α-Asarone involves evaluating supplier credibility. Key criteria include batch-specific purity reports (≥95% by HPLC), manufacturing facility audits, and compliance with REACH or similar frameworks. Prices fluctuate based on extraction methods (natural vs. synthetic) and order volume. For research or small-scale industrial use, 100g–1kg quantities are common, while large-scale buyers may negotiate contracts for drum or IBC-container shipments. Sample testing for odor profile and residual solvents is advised before full procurement.
