Description

(2-Bromo-3-Chlorophenyl)Hydrazine Hydrochloride is a high-purity, halogenated aromatic hydrazine derivative, primarily used as a critical synthetic intermediate in advanced organic chemistry. Its value lies in providing a functionalized aromatic scaffold for constructing complex heterocyclic systems and active pharmaceutical ingredients (APIs). This compound is essential for R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop novel compounds.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, anti-infectives, and oncology.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides that require specific halogenated phenyl hydrazine motifs.
• Heterocyclic Chemistry: Serves as a precursor for the synthesis of indoles, pyrazoles, and other nitrogen-containing heterocycles, which are core structures in many bioactive molecules.
• Material Science Research: Employed in the development of organic ligands for catalysis and functional materials with specific electronic or optical properties.
• Chemical Reference Standard: Supplied as a high-purity standard for analytical method development and quality control in chemical manufacturing.

Quality Control

Our (2-Bromo-3-Chlorophenyl)Hydrazine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all critical quality attributes. Our production adheres to cGMP principles where applicable, supporting its use in regulated research and development.

Storage

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