Description

[1,1-Biphenyl]-2,2,5,5-Tetrol(9Ci) CAS NO 4371-32-8 is a high-purity polyphenolic compound characterized by its four hydroxyl groups on a biphenyl scaffold. This unique structure makes it a valuable advanced intermediate and building block for the synthesis of complex organic molecules, particularly in fine chemical and pharmaceutical research. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries for creating novel ligands, polymers, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Serves as a critical precursor in the synthesis of complex drug molecules, particularly those requiring rigid, functionalized aromatic systems.
• Ligand Synthesis: Used to develop novel chelating agents and catalysts for asymmetric synthesis and metal-organic frameworks (MOFs).
• Polymer Chemistry: Acts as a monomer or cross-linking agent for producing high-performance, heat-resistant resins and specialty polymers.
• Agrochemical Research: Employed as a building block for developing new active ingredients with specific biological activity.
• Material Science: Investigated for use in organic electronic materials, such as hole-transport layers or as a component in advanced composites.
• Analytical Chemistry: May be used as a standard or reagent in analytical methods development due to its distinct polyphenolic structure.

Quality Control

Our [1,1-Biphenyl]-2,2,5,5-Tetrol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its nature as an easily oxidized compound, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability.
