Description

2,4-Dichlorophenylhydrazine Hydrochloride is a key organic intermediate and analytical reagent, primarily valued for its role as a versatile building block in heterocyclic synthesis. Its significance lies in its ability to form hydrazone derivatives, which are crucial precursors for the production of various pharmaceuticals, agrochemicals, and dyes. This compound is essential for R&D chemists and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity intermediates for complex synthesis.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing pyrazole, indazole, and other nitrogen-containing heterocycles.
• Agrochemical Synthesis: Used in the manufacturing of herbicides, fungicides, and plant growth regulators, leveraging its dichlorophenyl moiety for biological activity.
• Dye and Pigment Production: Serves as a coupling agent in the synthesis of azo dyes and complex organic pigments.
• Analytical Chemistry: Employed as a derivatization reagent for the identification and quantification of carbonyl compounds (aldehydes and ketones) via hydrazone formation.
• Research & Development: A valuable tool in academic and industrial R&D for exploring new synthetic pathways and novel chemical entities.
• Chemical Reference Standard: Used as a high-purity standard for analytical method development and quality control in chemical manufacturing.

Quality Control

Our 2,4-Dichlorophenylhydrazine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for synthetic applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and physical characteristics. Our quality commitment ensures batch-to-batch consistency and reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Recommended long-term storage temperature is 2-8°C.
