Description

Hexadecyl 4-Chlorobutyrate is a high-purity organic ester compound, also known by its CAS number 68516-31-4. This specialty chemical serves as a versatile intermediate and functional additive, valued for its unique combination of a long alkyl chain and a reactive chlorobutyl moiety. It is primarily sought by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring lipophilic modification, controlled reactivity, or as a building block for more complex molecules.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where its lipophilic nature can enhance bioavailability.
• Agrochemical Synthesis: Acts as a key intermediate in the production of certain herbicides, fungicides, and plant growth regulators.
• Polymer & Material Science: Functions as a monomer or plasticizer precursor in the development of specialty polymers, coatings, and resins.
• Surfactant & Emulsifier Precursor: Utilized in the manufacture of specialty surfactants and emulsifying agents for industrial formulations.
• Lubricant & Fuel Additive Component: Serves as a building block for high-performance lubricant additives and fuel system cleaners.
• Organic Synthesis Reagent: Employed in research and development as a reagent for introducing the hexadecyloxycarbonylpropyl group into target molecules.

Quality Control

Our Hexadecyl 4-Chlorobutyrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and impurity profiles. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing the results of tests such as assay (HPLC/GC), identity (IR, NMR), and specific impurity limits.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in darkness.
