Description

4-Hydrazinomethyl-Benzoic Acid is a versatile aromatic hydrazine derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both a reactive hydrazine group and a carboxylic acid moiety, makes it invaluable for constructing complex molecular architectures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to develop active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring hydrazide or hydrazone linkages.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators.
• Polymer Chemistry: Acts as a monomer or cross-linking agent for producing specialty polyamides, polyhydrazides, and other functional polymers.
• Chelating Agent Precursor: Serves as a starting material for synthesizing ligands and chelating agents used in metal catalysis and extraction.
• Bioconjugation & Labeling: Utilized in biochemical research for protein modification, antibody-drug conjugate (ADC) development, and fluorescent probe synthesis.
• Material Science: Building block for creating organic frameworks, coatings, and advanced materials with specific surface properties.

Quality Control

Our 4-Hydrazinomethyl-Benzoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, the container should be kept sealed under positive pressure of inert gas after opening to maintain product integrity.
