Description

3-Chloro-4-Fluorophenylhydrazine Hydrochloride is a high-purity, halogenated phenylhydrazine derivative used as a critical synthetic intermediate in advanced organic synthesis. This compound matters for its role in constructing complex heterocyclic scaffolds, particularly in the development of active pharmaceutical ingredients (APIs) and agrochemicals. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require reliable, high-quality building blocks for their R&D and production processes.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those containing pyrazole, indazole, or other nitrogen-containing heterocycles.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where the chloro-fluoro-phenyl moiety imparts specific biological activity.
• Dyestuff and Pigment Manufacturing: Serves as a precursor for azo dyes and high-performance pigments, contributing to color fastness and stability.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new chemical entities and reaction pathways in medicinal and synthetic chemistry.
• Material Science: Potential intermediate in the synthesis of specialty polymers and functional materials requiring specific aromatic architectures.

Quality Control

Our 3-Chloro-4-Fluorophenylhydrazine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for use as a pharmaceutical intermediate. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
