Description

4-Phenoxybutyl Chloride is a versatile organic halide building block used in fine chemical synthesis. Its value lies in its reactive chlorobutyl chain, which facilitates the introduction of the phenoxybutyl moiety into more complex molecular architectures. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing active ingredients and advanced intermediates.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring phenoxyalkylamine or ether-linked side chains.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the phenoxybutyl group imparts specific biological activity.
• Liquid Crystal & OLED Material Precursor: Serves as an intermediate in the manufacture of specialty chemicals for electronic displays and organic light-emitting diodes.
• Polymer Modification Agent: Employed to introduce functional groups into polymers or as a monomer/chain extender in specialty polymer production.
• Organic Synthesis Reagent: A versatile alkylating agent in research laboratories for nucleophilic substitution reactions to form carbon-carbon and carbon-heteroatom bonds.
• Fragrance & Flavor Intermediate: Used in the multi-step synthesis of complex aroma chemicals and flavor compounds.

Quality Control

Our 4-Phenoxybutyl Chloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee it meets the stringent requirements for use in advanced synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
