Description

2-Chloro-6-Nitrotoluene-4-Sulphonic Acid is a key sulfonated aromatic intermediate with a chloronitro-substituted toluene backbone. This compound matters for its role as a versatile building block in the synthesis of more complex molecules, particularly dyes, pigments, and agrochemicals. It is primarily needed by manufacturers in the fine chemical, specialty dye, and agricultural chemical industries seeking reliable, high-purity intermediates for their production processes.

Application

• Dye and Pigment Intermediate: A crucial precursor in the synthesis of azo dyes, acid dyes, and other complex colorants.
• Agrochemical Synthesis: Used as a building block for manufacturing certain herbicides, fungicides, and plant growth regulators.
• Pharmaceutical Intermediates: Serves in the multi-step synthesis of specific active pharmaceutical ingredients (APIs).
• Chemical Research & Development: Employed in organic synthesis laboratories for developing novel sulfonated compounds.
• Photographic Chemicals: Can be utilized in the production of certain light-sensitive chemicals used in imaging.
• Polymer Modification: Acts as a functional monomer or additive to introduce sulfonic acid groups into polymer chains.

Quality Control

Our 2-Chloro-6-Nitrotoluene-4-Sulphonic Acid is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for industrial and fine chemical applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use. Recommended storage temperature is 15-25°C. Keep away from strong bases and reducing agents.
