Description

5-Acetylamino-2-Chloro-4-Sulfobenzoic Acid is a high-purity, functionalized benzoic acid derivative of significant industrial importance. This compound serves as a versatile and critical chemical intermediate in the synthesis of more complex molecules, particularly in the pharmaceutical and specialty chemical sectors. It is primarily sought after by manufacturers and R&D teams in the pharmaceutical, agrochemical, and dyestuff industries for its reactive functional groups which enable precise chemical modifications.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a sulfonated or chlorinated benzoic acid core.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators where its specific substitution pattern imparts desired biological activity.
• Dyestuff and Pigment Manufacturing: Acts as a precursor for azo dyes and other complex colorants, contributing to color fastness and specific hue properties.
• Research & Development: Essential reagent in organic chemistry research for constructing novel molecular architectures in academic and industrial laboratories.
• Specialty Chemical Production: Intermediate for surfactants, corrosion inhibitors, and other performance chemicals that benefit from its anionic sulfonic acid group.

Quality Control

Our 5-Acetylamino-2-Chloro-4-Sulfobenzoic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive synthesis applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request 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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and handling properties.
