Description

4-[2,4-Bis(1,1-Dimethylpropyl)Phenoxy]Butyryl Chloride is a specialized organic acid chloride derivative, serving as a critical building block for the synthesis of complex molecules. Its value lies in its ability to introduce the bulky, lipophilic 2,4-bis(1,1-dimethylpropyl)phenoxy moiety into target compounds, modifying their physical and chemical properties. This intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly for developing active ingredients and functional additives.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), especially those requiring sterically hindered phenolic groups for enhanced metabolic stability or receptor binding.
• Agrochemical Synthesis: Used to create advanced herbicides, fungicides, and plant growth regulators where the bulky phenoxy group can influence bioavailability and environmental persistence.
• Polymer Modification: Acts as a functional monomer or chain terminator in the production of specialty polymers, imparting specific characteristics like UV stability or altered solubility.
• Ligand and Catalyst Development: Employed in organometallic chemistry to synthesize sophisticated ligands for catalytic systems used in asymmetric synthesis.
• Dye and Pigment Manufacturing: Intermediate for creating specialized colorants with improved lightfastness and compatibility properties.
• Research & Development: A valuable tool in academic and industrial R&D for exploring new chemical entities and material science applications.

Quality Control

Our production of 4-[2,4-Bis(1,1-Dimethylpropyl)Phenoxy]Butyryl Chloride adheres to stringent in-process and final quality controls to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including HPLC, GC, and NMR for precise characterization. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and ensure maximum shelf life. Keep away from heat, sparks, and open flame.
