Description

4-Chlorobutyldimethylchlorosilane is a versatile bifunctional organosilicon reagent featuring both a reactive chlorosilane group and a terminal chloroalkyl chain. This dual functionality makes it a critical intermediate for introducing silicon-containing moieties and creating custom silane coupling agents. It is essential for manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors seeking to develop novel compounds with tailored surface properties or as synthetic building blocks.

Application

• Silane Coupling Agent Precursor: Serves as a key intermediate for synthesizing custom silane coupling agents used to improve adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Pharmaceutical Intermediate: Utilized in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where the silicon moiety can influence pharmacokinetics.
• Surface Modification Agent: Used to functionalize silica, nanoparticles, and other substrates to alter surface energy, compatibility, or reactivity.
• Polymer & Resin Modifier: Incorporated into silicone polymers and specialty resins to introduce cross-linking sites or chlorobutyl functional groups, enhancing material properties.
• Agrochemical Synthesis: Acts as a building block in the production of certain herbicides, fungicides, and plant growth regulators.
• Research & Development: A valuable tool in organic and materials chemistry R&D for creating novel silicon-based compounds and hybrid materials.

Quality Control

Our 4-Chlorobutyldimethylchlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat 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: 2-8°C for extended stability.
