Description

4-Phenylbutyryl Chloride is an important organic acid chloride intermediate used in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. Its high reactivity makes it a valuable building block for introducing the 4-phenylbutyryl moiety into target molecules, enabling the creation of compounds with specific biological or material properties. This product is essential for research and development laboratories, as well as production facilities in the pharmaceutical and fine chemical industries, where precise and reliable intermediates are required.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting metabolic and neurological disorders.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators.
• Peptide Chemistry: Serves as an acylating agent for the modification of amino acids and peptides.
• Polymer & Material Science: Employed in the synthesis of specialty monomers, polymers, and liquid crystals.
• Organic Synthesis Reagent: A versatile reagent for Friedel-Crafts acylation and other nucleophilic substitution reactions in research.
• Chemical Research: Utilized in academic and industrial R&D for exploring new chemical entities and reaction pathways.

Quality Control

Our 4-Phenylbutyryl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic and highly volatile nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature is 2-8°C for long-term stability.
