Description

Methyl 2,5-Dichlorobenzenesulphonate CAS NO 78150-04-6 is a specialized organic sulfonate ester, serving as a versatile chemical intermediate and building block in advanced synthesis. Its value lies in its unique molecular structure, which incorporates both a sulfonate ester group and strategically placed chlorine atoms, enabling selective reactions for constructing complex molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to develop active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for compounds requiring a benzenesulfonate core.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides, leveraging the dichloro-substituted aromatic system.
• Chemical Research & Development: A valuable reagent in organic synthesis for introducing the methyl sulfonate moiety or for further functionalization via the chlorine atoms.
• Dye and Pigment Manufacturing: Intermediate in the synthesis of specialized dyes and colorants where sulfonate groups enhance solubility and binding properties.
• Polymer Modification: Acts as a monomer or cross-linking agent in the production of specialty polymers and resins.
• Liquid Crystal and Electronic Material Precursor: Used in the development of advanced materials for display technologies and organic electronics.

Quality Control

Our Methyl 2,5-Dichlorobenzenesulphonate is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC, GC, and NMR, to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from heat sources and incompatible materials.
