Description

4-Amino-3-Nitrobenzaldehyde is a versatile aromatic aldehyde and nitroaniline derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both an aldehyde and an aromatic amine group, makes it a valuable precursor for creating complex heterocyclic compounds and functional dyes. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop new active ingredients and high-performance materials.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of various active pharmaceutical ingredients (APIs), particularly those containing benzimidazole or quinoxaline cores.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents where its nitro and amino groups facilitate further functionalization.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other complex colorants, contributing to color fastness and specific hue properties.
• Organic Light-Emitting Diodes (OLEDs): Acts as a building block for electron-transport materials and emissive layer components in electronic displays.
• Corrosion Inhibitor Formulation: Utilized in the development of specialized corrosion inhibitors for industrial applications.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new chemical entities and reaction pathways.

Quality Control

Our 4-Amino-3-Nitrobenzaldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) detailing all test results are 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 nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation. Keep away from heat, sparks, and open flame.
