Description

Benzyl [4-(Chlorosulfonyl)Phenyl]Carbamate is a specialized organic intermediate featuring both a carbamate and a reactive chlorosulfonyl functional group. This unique bifunctional structure makes it a valuable building block for synthesizing more complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists working on sulfonamide-based active ingredients, novel polymer modifiers, and advanced material science applications.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of sulfonamide-containing drug candidates for various therapeutic areas.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides that utilize the sulfonamide pharmacophore.
• Polymer Modification: Serves as a functional monomer or cross-linking agent to introduce sulfonyl chloride groups into polymer backbones for specialty materials.
• Chemical Biology Probes: Employed in research to create activity-based probes or affinity labels for studying enzyme function.
• Dye and Pigment Intermediate: Acts as a building block for synthesizing sulfonated dyes and specialty colorants.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis projects requiring the introduction of a protected amine and a sulfonyl chloride handle.

Quality Control

Every batch of Benzyl [4-(Chlorosulfonyl)Phenyl]Carbamate is manufactured and tested under strict quality management protocols to ensure consistency and reliability for your synthetic processes. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity (HPLC), identity (IR, NMR), and impurity profiles. Our quality system is designed to support cGMP and ISO standards for advanced intermediates.

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). This compound is hygroscopic (moisture-sensitive); therefore, 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, sparks, and open flame.
