Description

3-Chloro-4-Hydroxybenzohydrazide is a versatile organic intermediate featuring both a hydrazide and a phenolic hydroxyl group on a chlorinated benzene ring. This unique structure makes it a valuable building block for synthesizing more complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily sought after by research and development chemists and process engineers for creating active pharmaceutical ingredients (APIs), crop protection agents, and functional dyes.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of heterocyclic compounds, hydrazones, and other active molecules with potential therapeutic applications.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators, leveraging its reactive hydrazide moiety.
• Dye and Pigment Manufacturing: Serves as a coupling agent or a core structure for producing azo dyes and other colorants with specific light-fastness properties.
• Chemical Research & Development: A valuable reagent in academic and industrial R&D for exploring new synthetic pathways and material science applications.
• Coordination Chemistry: Acts as a ligand for metal ions, useful in catalysis and the preparation of metal-organic frameworks (MOFs).

Quality Control

Our 3-Chloro-4-Hydroxybenzohydrazide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. For long-term storage, consider using an inert atmosphere to minimize oxidation.
