Description

2-Chloro-p-Phenylenediamine Dihydrochloride is a high-purity, dihydrochloride salt derivative of a halogenated aromatic diamine, serving as a critical synthetic intermediate and analytical reagent. Its value lies in providing a stable, soluble, and reactive form of the parent diamine, essential for controlled chemical synthesis and precise analytical applications. This compound is primarily needed by manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and specialty dye industries for the development of active ingredients and complex organic molecules.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a halogenated aniline moiety.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where its chlorinated aromatic structure imparts specific biological activity.
• Hair Dye and Cosmetic Pigment Precursor: Acts as a primary intermediate in the manufacture of oxidation hair dyes and permanent cosmetic colorants.
• Polymer and Resin Modifier: Serves as a curing agent or cross-linking monomer in the production of specialty polyurethanes, epoxies, and high-performance polymers.
• Analytical Reagent and Reference Standard: Employed in HPLC, LC-MS, and other chromatographic methods as a standard for quality control and research in related chemical processes.
• Research & Development: Utilized in academic and industrial R&D for exploring new organic reactions, catalysis, and material science applications.

Quality Control

Our 2-Chloro-p-Phenylenediamine Dihydrochloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for synthetic and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 performance.
