Description

Benzenepropanoyl Chloride, 3-Fluoro- is a specialized aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its primary value lies in its dual reactive sites, enabling the efficient introduction of both a fluorinated phenyl moiety and a versatile acyl chloride functional group into target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries, where it is used to develop novel active ingredients and high-performance polymers.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of fluorinated drug candidates, including protease inhibitors and CNS-active compounds.
• Agrochemical Synthesis: Used to construct advanced fluorinated herbicides, fungicides, and plant growth regulators.
• Liquid Crystal & OLED Material Production: Serves as a building block for fluorinated aromatic cores in electronic display and lighting materials.
• Polymer & Resin Modification: Employed to introduce fluorinated aromatic units into polymer chains, enhancing thermal stability and chemical resistance.
• Peptide & Protein Research: Acts as an acylating agent for modifying amino acids or introducing fluorinated probes in biochemical studies.
• Custom Synthesis & Contract Manufacturing: A valuable starting material for bespoke chemical synthesis services targeting fluorinated aromatic compounds.

Quality Control

Every batch of Benzenepropanoyl Chloride, 3-Fluoro- is produced under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request. We adhere to cGMP principles where applicable to support our clients in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong bases, oxidizers, and sources of ignition.
