Description

5-Chlorooctafluoropentanoic Acid is a highly fluorinated carboxylic acid derivative, serving as a critical building block for advanced materials and specialty chemicals. Its unique perfluorinated backbone and reactive acid chloride precursor capability make it invaluable for introducing specific fluorinated segments into target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and high-performance polymer industries seeking to enhance product properties such as chemical resistance, thermal stability, and bioavailability.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing fluorinated moieties to improve metabolic stability and membrane permeability.
• Agrochemical Synthesis: Serves as a key precursor for developing novel herbicides and pesticides with enhanced environmental persistence and efficacy.
• Fluorinated Surfactant & Polymer Production: A vital monomer for creating specialty surfactants, coatings, and elastomers with exceptional oil, water, and chemical resistance.
• Liquid Crystal & Electronic Material: Employed in the manufacture of fluorinated liquid crystals and dielectric fluids for advanced display technologies and electronics.
• Organic Synthesis Reagent: Acts as a versatile reagent for synthesizing complex fluoroorganic compounds in academic and industrial R&D settings.
• Surface Modification Agent: Used to impart hydrophobic and oleophobic properties to textiles, membranes, and other substrates.

Quality Control

Every batch of 5-Chlorooctafluoropentanoic Acid is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards and customer-specific requirements. Comprehensive analytical testing, including assay, purity, and identity confirmation, is performed. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and product integrity.

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). This material is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; ensure containers are kept tightly sealed to exclude moisture and stored separately from bases and oxidizing agents.
