Description

4-Chloroanilinium Hydrogen Sulphate is an important organic salt and synthetic intermediate derived from 4-chloroaniline. This compound matters for its role as a stable, non-volatile precursor in complex organic synthesis, offering a convenient source of the 4-chloroanilinium cation. It is primarily needed by manufacturers in the pharmaceutical, agrochemical, and specialty dye industries for the production of active ingredients and complex molecules.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of various active pharmaceutical ingredients (APIs), including certain analgesics and antimicrobial agents.
• Agrochemical Synthesis: Used in the production of herbicides, pesticides, and plant growth regulators where the 4-chloroaniline moiety is required.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other complex colorants, providing chromophore and auxochrome groups.
• Chemical Research & Development: Employed in academic and industrial R&D labs for exploring new organic reactions and creating novel compound libraries.
• Polymer Industry: Can be utilized in the synthesis of specialty monomers or as a curing agent/modifier for certain polymer systems.

Quality Control

Our 4-Chloroanilinium Hydrogen Sulphate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting purity, physical characteristics, and test results are provided with every shipment.

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.
