Description

Urushiol (15:1) is a specific alkylcatechol compound, a key constituent of natural lacquers and a potent contact allergen. This high-purity reference standard is essential for research and development in dermatology, immunology, and material science. It is primarily sought by pharmaceutical R&D teams, academic researchers, and specialty chemical manufacturers for its precise biological activity and structural properties.

Application

• Biomedical Research: Critical reference standard for studying Type IV hypersensitivity reactions, contact dermatitis mechanisms, and immune response pathways.
• Pharmaceutical Development: Used in the development and validation of assays for anti-inflammatory agents, topical treatments, and desensitization therapies.
• Toxicology & Safety Testing: Employed as a positive control in skin sensitization tests (e.g., Local Lymph Node Assay - LLNA) for consumer products and chemicals.
• Material Science: Serves as a model compound for studying the polymerization and durable coating properties of natural urushiol-based lacquers.
• Botanical & Natural Product Analysis: Used as an analytical standard for the identification and quantification of urushiol congeners in plants like poison ivy, poison oak, and lacquer trees.

Quality Control

Our Urushiol (15:1) is produced under strict quality management protocols. Each batch is characterized and tested to ensure identity, purity, and stability, meeting the exacting standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC), identity confirmation (by IR, NMR), and related substance profile is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label or COA. This product is easily oxidized and light-sensitive; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and purity.
