Description

p-(Dodecyloxy)Benzenesulphonyl Chloride is a specialized organic intermediate featuring a long-chain alkyloxy group attached to a reactive benzenesulfonyl chloride core. This molecular structure makes it a valuable building block for introducing hydrophobic, surfactant-like properties into target molecules. It is particularly sought after by manufacturers in the agrochemical, pharmaceutical, and specialty chemical industries for synthesizing sulfonamide derivatives, surfactants, and liquid crystal compounds.

Application

• Agrochemical Intermediates: Key precursor in the synthesis of novel herbicides, fungicides, and plant growth regulators that require specific hydrophobic characteristics.
• Pharmaceutical Synthesis: Used to create sulfonamide-based active pharmaceutical ingredients (APIs) and prodrugs, where the dodecyloxy chain can influence bioavailability and lipophilicity.
• Specialty Surfactants & Detergents: Serves as a critical intermediate for manufacturing anionic surfactants with unique emulsifying and wetting properties for industrial and cosmetic formulations.
• Liquid Crystal Materials: Acts as a building block for mesogenic compounds used in display technologies, leveraging its elongated molecular structure.
• Polymer Modification: Employed to functionalize polymers via sulfonylation, imparting specific surface-active or compatibilizing qualities.
• Dye & Pigment Synthesis: Intermediate in the production of specialized dyes and pigments where sulfonyl chloride groups are used for covalent bonding.
• Research & Development: A valuable reagent in organic chemistry R&D for exploring new synthetic pathways and creating novel chemical entities.

Quality Control

Our p-(Dodecyloxy)Benzenesulphonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets precise specifications for critical applications. Certificates of Analysis (COA) detailing all test results are available upon request, providing full traceability and compliance assurance for your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under dry conditions to prevent hydrolysis. Keep away from strong bases, amines, and oxidizing agents.
