Description

Sodium 2-Chloro-5-Nitrobenzenesulfonate is a high-purity, water-soluble sodium salt of a substituted benzenesulfonic acid, serving as a critical synthetic intermediate. This compound matters for its role in facilitating the production of dyes, pigments, and other complex organic molecules through its reactive sulfonate and nitro functional groups. It is primarily needed by manufacturers in the chemical synthesis, dye and pigment, and pharmaceutical intermediate industries seeking reliable and consistent raw materials for their processes.

Application

• Dye and Pigment Intermediate: A key precursor in the synthesis of azo dyes, acid dyes, and other colorants, particularly yellow and red shades.
• Pharmaceutical Synthesis: Used as a building block for creating active pharmaceutical ingredients (APIs) and other fine chemicals.
• Chemical Research & Development: Employed in organic synthesis laboratories for developing new compounds and methodologies.
• Agrochemical Intermediates: Serves as a starting material in the production of certain herbicides and plant protection agents.
• Photographic Chemicals: Can be utilized in the formulation of specific photographic developers and sensitizers.
• Corrosion Inhibitor Precursor: Acts as an intermediate in the manufacture of specialty chemicals used for metal surface treatment.

Quality Control

Our Sodium 2-Chloro-5-Nitrobenzenesulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and composition. Certificates of Analysis (COA) documenting results for assay, impurity profile, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
