Description

Bis(Heptafluorobutyric Acid)(-)-4-[2-[n-(Heptafluorobutyryl)-n-Methylamino]-1-[(Heptafluorobutyryl)Oxy]Ethyl]-1,2-Phenylene Ester is a specialized fluorinated organic compound designed for advanced synthetic and analytical applications. Its complex structure, featuring multiple heptafluorobutyryl groups, makes it a valuable reagent for introducing fluorinated moieties, which can dramatically alter the physical and chemical properties of target molecules. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical sectors, particularly for developing novel active ingredients with enhanced metabolic stability, bioavailability, and lipophilicity.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of fluorinated active pharmaceutical ingredients (APIs), especially for central nervous system (CNS) and anti-inflammatory drugs.
• Agrochemical Synthesis: Used to create advanced fluorinated pesticides and herbicides, where the fluorine atoms improve weather resistance and biological activity.
• Derivatization Agent for Analytics: Serves as a powerful derivatization reagent in Gas Chromatography (GC) and Liquid Chromatography-Mass Spectrometry (LC-MS) for enhancing the detection of amines, alcohols, and other analytes.
• Material Science Research: Employed in the development of specialty fluoropolymers and surface modification agents to impart oil, water, and stain resistance.
• Positron Emission Tomography (PET) Tracer Precursor: Potential use in the synthesis of fluorine-18 labeled radiopharmaceuticals for medical imaging.
• Liquid Crystal & Electronic Chemical Synthesis: Intermediate for producing fluorinated components used in liquid crystal displays (LCDs) and dielectric materials.

Quality Control

Our Bis(Heptafluorobutyric Acid) Ester is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis using advanced techniques including HPLC, GC, NMR, and Mass Spectrometry to confirm identity, potency, and impurity profiles. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting compliance with customer specifications. Production can be aligned with cGMP guidelines for pharmaceutical applications upon request.

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 hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, open flame, and incompatible materials such as strong bases and oxidizing agents.
