Description

Octadecyl Chloroformate is a versatile long-chain alkyl chloroformate ester, a key reagent for introducing the octadecyl (stearyl) moiety. This compound matters for its role as a crucial intermediate in the synthesis of specialty chemicals, enabling precise molecular modifications. It is primarily needed by manufacturers in the pharmaceutical, agrochemical, and polymer industries for applications such as derivatization, surface modification, and the production of functional materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs and active pharmaceutical ingredients (APIs) requiring lipophilic side chains for enhanced bioavailability.
• Agrochemical Synthesis: Serves as a key building block for creating pesticides, herbicides, and plant growth regulators with tailored properties.
• Polymer Modification: Employed to functionalize polymers and resins, imparting hydrophobic characteristics or creating reactive sites for further cross-linking.
• Surface Derivatization Agent: Utilized to modify the surface of silica, glass, or other materials to create hydrophobic coatings or chromatographic stationary phases.
• Analytical Chemistry Reagent: Acts as a derivatization agent in gas chromatography (GC) and high-performance liquid chromatography (HPLC) for the analysis of amines, alcohols, and other compounds.
• Specialty Surfactant Production: A precursor in the manufacture of specialty ester-based surfactants and emulsifiers.

Quality Control

Our Octadecyl Chloroformate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling by gas chromatography (GC), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent degradation from moisture. Keep away from heat, sparks, and open flame.
