Description

4-(Hexadecylamino)Benzoyl Chloride is a high-purity, long-chain fatty acid derivative benzoyl chloride used as a critical building block in advanced organic synthesis. This compound is valued for its ability to introduce a lipophilic hexadecylamino-benzoyl moiety, enabling the modification of material properties and biological activity. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and specialty chemical industries for developing surfactants, liquid crystals, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting lipid membranes or requiring enhanced bioavailability.
• Agrochemical Synthesis: Used to create specialized surfactants and adjuvants that improve the efficacy and delivery of pesticides and herbicides.
• Specialty Surfactants & Emulsifiers: Serves as a raw material for producing non-ionic and cationic surfactants with unique hydrophobic-lipophilic balance (HLB) properties.
• Liquid Crystal Materials: A valuable intermediate in the production of thermotropic liquid crystals for display technologies and optical devices.
• Polymer Modification: Employed to functionalize polymers, imparting specific surface characteristics or compatibility with other materials.
• Research & Development: Essential tool in organic chemistry labs for studying structure-activity relationships (SAR) and developing new chemical entities.
• Dye & Pigment Industry: Used in the synthesis of specialized dyes and pigments requiring hydrophobic side chains for stability and performance.

Quality Control

Every batch of 4-(Hexadecylamino)Benzoyl Chloride is manufactured under strict quality management systems and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our standard grade meets high-purity specifications suitable for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, 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, 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 or argon) after opening to prevent degradation. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and water.
