Description

Benzenepentanoic Acid, 3-Hydroxy- is a versatile aromatic carboxylic acid derivative characterized by its pentanoic acid chain and a phenolic hydroxyl group. This unique bifunctional structure makes it a valuable intermediate and building block in advanced organic synthesis, particularly for creating complex molecules with specific functional properties. It is primarily utilized by pharmaceutical, agrochemical, and specialty chemical industries for research and development as well as production-scale applications.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring a lipophilic aromatic backbone with a modifiable hydroxyl group.
• Agrochemical Synthesis: Used in the development and production of herbicides, fungicides, and plant growth regulators where its structure contributes to biological activity.
• Liquid Crystal & Polymer Chemistry: Acts as a monomer or modifying agent in the production of specialty polymers, resins, and liquid crystal materials.
• Organic Synthesis Building Block: Employed in research laboratories for constructing more complex organic compounds, including dyes, pigments, and fine chemicals.
• Bioconjugation & Linker Chemistry: The carboxylic acid and hydroxyl groups provide handles for conjugation, useful in developing biochemical probes and drug delivery systems.

Quality Control

Our Benzenepentanoic Acid, 3-Hydroxy- is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with detailed specifications for each shipment, supporting compliance in regulated applications. Specifications can be aligned with research, technical, or pharmaceutical intermediate grade requirements.

Storage

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