Description

2,4-Dichlorophenylhydrazine is a versatile aromatic hydrazine derivative that serves as a critical building block in advanced organic synthesis. Its value lies in its dual functionality, acting as a key precursor for the synthesis of heterocyclic compounds and as a derivatization agent for analytical chemistry. This high-purity intermediate is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where reliable quality and consistent supply are paramount.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of various heterocyclic compounds, including pyrazoles and indazoles, which are core structures in active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators, leveraging the dichlorophenyl moiety for biological activity.
• Analytical Chemistry: Employed as a derivatizing agent for the detection and quantification of carbonyl compounds (aldehydes and ketones) via hydrazone formation in HPLC and GC analysis.
• Dye and Pigment Manufacturing: Serves as an intermediate in the synthesis of azo dyes and other complex colorants.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new synthetic pathways and creating novel chemical entities.
• Polymer Chemistry: Can be utilized as a monomer or chain modifier in the synthesis of specialized polymers.

Quality Control

Our 2,4-Dichlorophenylhydrazine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, 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, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature (store under inert atmosphere), it is recommended to store the product under an inert gas (nitrogen or argon) for long-term stability. Keep away from heat, sparks, open flames, and strong oxidizing agents.
