Description

Benzophenone-4'-Heptyl-4-Pentanoic Acid CAS NO 128596-01-0 is a specialized organic compound belonging to the benzophenone derivative family. This chemical serves as a critical intermediate and functional additive, valued for its unique molecular structure that combines a benzophenone core with an extended aliphatic chain terminated by a carboxylic acid group. It is primarily sought after by R&D laboratories and industrial manufacturers in the pharmaceutical, polymer, and specialty chemical sectors for synthesizing advanced materials, UV stabilizers, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates and active pharmaceutical ingredients (APIs).
• Polymer Additive: Used as a monomer or functional modifier in the production of specialty polymers and coatings to impart specific properties.
• UV Absorber / Light Stabilizer Precursor: Serves as a core structure for developing advanced UV filters and stabilizers for plastics, paints, and personal care formulations.
• Organic Synthesis Reagent: Employed in research and development for constructing complex organic molecules, particularly those requiring a lipophilic benzophenone moiety.
• Liquid Crystal & Electronic Material Intermediate: Potential use in the synthesis of components for liquid crystal displays (LCDs) and other electronic materials.
• Cross-linking Agent: Can function as a cross-linker in polymer chemistry due to its reactive carboxylic acid group.

Quality Control

Our Benzophenone-4'-Heptyl-4-Pentanoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and rigorous control of residual solvents and heavy metals. We provide full traceability and Certificates of Analysis (COA) are available upon request to ensure compliance with your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong acids and incompatible materials such as strong oxidizing agents. The container must be kept tightly sealed due to potential sensitivity to moisture.
