Description

4,4'-Dihydroxystilbene is an organic compound belonging to the stilbene class, characterized by its two phenolic hydroxyl groups. This structure makes it a valuable intermediate and building block in the synthesis of more complex molecules, particularly those requiring a rigid, conjugated backbone. It is primarily sought after by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for research and production purposes. The compound's properties necessitate careful handling and storage to maintain its integrity and performance.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of various active pharmaceutical ingredients (APIs), including potential candidates for hormone-related therapies.
• Agrochemical Synthesis: Used in the production of certain fungicides and plant growth regulators that leverage its stilbene core structure.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the development of specialty polymers, resins, and liquid crystal materials.
• UV Absorber & Stabilizer Precursor: Acts as a chemical precursor in the manufacture of compounds used to protect materials from ultraviolet light degradation.
• Fluorescent Whitening Agent (FWA) Intermediate: Utilized in the synthesis of optical brighteners for paper, textiles, and detergents.
• Research & Development: Employed in academic and industrial R&D for studying antioxidant properties, photochemistry, and as a model compound in organic synthesis.

Quality Control

Our 4,4'-Dihydroxystilbene is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets precise specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes. We are committed to consistent quality and supply reliability for your production and research needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
