Description

2-Phenoxybutyryl Chloride is an important organic acid chloride intermediate used in the synthesis of various fine chemicals and active pharmaceutical ingredients (APIs). Its core value lies in its high reactivity, enabling efficient acylation reactions to introduce the phenoxybutyryl moiety into target molecules. This compound is primarily needed by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for research, development, and production processes.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing novel drug candidates and active pharmaceutical ingredients (APIs), particularly in cardiovascular and central nervous system (CNS) therapeutic areas.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators, where the phenoxybutyric acid derivative is a critical functional group.
• Polymer Chemistry: Serves as a monomer or modifier in the synthesis of specialty polymers, resins, and coatings to impart specific chemical resistance or physical properties.
• Liquid Crystal & OLED Materials: Acts as a precursor in the manufacture of advanced electronic materials, including liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs).
• Dye & Pigment Manufacturing: Employed in the synthesis of complex organic dyes, pigments, and photographic chemicals.
• Chemical Research & Development: A versatile reagent in academic and industrial R&D laboratories for exploring new synthetic pathways and creating novel chemical entities.

Quality Control

Our 2-Phenoxybutyryl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of our global customer base. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request.

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 hygroscopic (moisture-sensitive) nature and classification as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition from moisture ingress. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and oxidizing agents.
