Description

2-Chloro-5-Fluorophenylhydrazine Hydrochloride is a high-purity, halogenated phenylhydrazine salt serving as a critical building block in advanced organic synthesis. Its value lies in providing a reactive hydrazine moiety adjacent to chloro and fluoro substituents, enabling the construction of complex heterocyclic scaffolds. This intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing new active ingredients.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those containing pyrazole, indazole, or other nitrogen-containing heterocycles.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and insecticides where the specific halogen pattern enhances bioactivity.
• Dyestuff and Pigment Manufacturing: Serves as a coupling agent for producing azo dyes and specialty pigments with specific color fastness and properties.
• Chemical Research & Development: A versatile reagent for exploring new reaction pathways and creating libraries of compounds for high-throughput screening.
• Material Science: Potential monomer or modifier in the synthesis of specialized polymers and functional materials.

Quality Control

Our 2-Chloro-5-Fluorophenylhydrazine Hydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. A detailed Certificate of Analysis (COA) documenting purity, assay, and impurity profiles is provided with every shipment.

Storage

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