Description

2-[2,4-Bis(1,1-Dimethylpropyl)Phenoxy]Butyryl Chloride is a specialized acyl chloride derivative, a key reactive intermediate in advanced organic synthesis. Its value lies in its ability to efficiently introduce the bulky, lipophilic 2,4-bis(1,1-dimethylpropyl)phenoxybutyryl moiety into target molecules, enabling the creation of compounds with specific steric and solubility properties. This product is essential for researchers and manufacturers in the agrochemical and pharmaceutical industries developing novel active ingredients, as well as for fine chemical producers creating custom ligands and functional materials.

Application

• Agrochemical Intermediate: A critical building block for the synthesis of novel herbicides, fungicides, and plant growth regulators, where its bulky organic group can influence bioavailability and environmental persistence.
• Pharmaceutical Synthesis: Used in the development of active pharmaceutical ingredients (APIs), particularly for creating prodrugs or modifying drug molecules to alter their pharmacokinetic profiles.
• Polymer Chemistry: Serves as a functional monomer or chain-transfer agent for producing specialty polymers with tailored surface properties and enhanced stability.
• Ligand and Catalyst Preparation: Employed in the synthesis of sophisticated ligands for metal-organic frameworks (MOFs) or asymmetric catalysis, leveraging its sterically demanding structure.
• Dye and Pigment Manufacturing: Acts as an intermediate for creating light-stable, high-performance colorants and imaging agents.
• Material Science Research: Utilized in surface modification and the creation of advanced organic materials with specific functional characteristics.

Quality Control

Our production of 2-[2,4-Bis(1,1-Dimethylpropyl)Phenoxy]Butyryl Chloride adheres to stringent internal quality standards to ensure batch-to-batch consistency and reliability for your synthetic processes. Every lot is analyzed using advanced techniques including HPLC, GC, and NMR to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment, and we support compliance with relevant regulatory frameworks such as REACH.

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). This compound is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and ensure maximum shelf life. Isolate from strong oxidizing agents, strong bases, and sources of heat.
