IUPAC Name: 1,3-Dimethoxy-5-pentylbenzene
Synonyms: 5-Pentyl-1,3-dimethoxybenzene; Olivetol dimethyl ether; 1,3-Dimethoxy-5-amylbenzene
Molecular Formula: C₁₃H₂₀O₂
Molecular Weight: 208.30 g/mol
Appearance: Off-white to yellow solid
Boiling Point: ~295-298°C
Solubility:
•Soluble in organic solvents (ethanol, methanol, DMSO, chloroform)
•Insoluble in water
Key Structural Features:
•Dimethyl-protected resorcinol core (methoxy groups at positions 1 and 3)
•n-Pentyl chain (-C₅H₁₁) at position 5
Functional Advantages & Applications
A. Primary Role: Protected Synthetic Intermediate
•Stability Enhancement: Methoxy groups prevent oxidation of phenolic hydroxyls, enabling long-term storage and simplified handling compared to olivetol.
•Synthetic Flexibility: Serves as a key precursor for:
•Cannabinoid synthesis (selective deprotection enables controlled functionalization)
•Pharmaceutical intermediates (alkylresorcinol-based bioactive molecules)
•Material science ligands (coordination chemistry frameworks)
B. Key Applications by Industry
| Industry | Application | Advantage |
| Pharmaceutical R&D | Cannabinoid analog production | Enables multi-step synthesis without degradation |
| Organic Chemistry | Building block for complex molecules | Stable under acidic/basic conditions |
| Chemical Biology | Probe development for receptor studies | Improved cell permeability vs. phenolics |
Synthetic Utility Comparison
| Property | Olivetol Dimethyl Ether | Olivetol (Free Phenol) |
| Stability | High (stable at RT for months) | Low (oxidizes rapidly; requires -20°C) |
| Handling | Standard laboratory conditions | Cryogenic storage/argon protection |
| Functionalization | Selective deprotection (e.g., BBr₃) | Direct coupling (pH-sensitive) |
| Synthetic Yield | Higher in multi-step sequences | Limited by degradation |
Safety & Handling
Storage Conditions:
•Stable at room temperature (no cryogenic requirement)
•Store in sealed containers under inert atmosphere (N₂/Ar)
Handling Precautions:
•Use standard PPE (gloves, goggles)
•Avoid prolonged skin contact (potential irritant)
Regulatory Status:
•Not controlled under international narcotics conventions
•Non-psychoactive and exempt from DEA scheduling
Our Advantage
Reducing energy consumption by 20% compared to industry averages.



Shipment Guidelines
Labeling: Include hazard symbols CAS number, and "Keep Away from Heat/Incompatible Substances" warnings.
Air Freight: Preferred for urgent shipments; ensure packages meet IATA Dangerous Goods Regulations (DGR) for organic peroxides .
Shipping Modes:
Expedited: 3–5 business days (e.g., DHL Express) for time-sensitive research projects.
Standard: 7–14 days via sea freight, cost-effective for bulk orders.
Storage Conditions:
Pre-Shipment: Store at 2–8°C if light-sensitive; avoid freezing to prevent crystallization.
In Transit: Maintain ambient temperature (15–25°C) with humidity <60%. Use data loggers for real-time monitoring.
Risk Mitigation: Include desiccants and oxygen absorbers in packaging. Avoid prolonged exposure to sunlight or electromagnetic fields.
