Description

2-Amino-5-Chlorobenzaldehyde is a versatile aromatic aldehyde and amine building block, essential for advanced organic synthesis. Its bifunctional nature makes it a critical intermediate for constructing complex heterocyclic and pharmaceutical scaffolds. This high-purity compound is primarily sought by research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with benzimidazole, quinazoline, or other fused heterocyclic structures.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators where the chlorinated aniline moiety is required.
• Dye and Pigment Manufacturing: Serves as a starting material for producing azo dyes and complex organic pigments, contributing to color fastness and specific hue properties.
• Ligand and Catalyst Development: Employed in the creation of novel Schiff base ligands for metal catalysis and coordination chemistry applications.
• Material Science Research: Utilized in the synthesis of organic semiconductors, conductive polymers, and advanced organic frameworks (MOFs/COFs).
• Chemical Research & Development: A fundamental building block for custom synthesis, medicinal chemistry, and process optimization in contract research organizations (CROs) and academic labs.

Quality Control

Our 2-Amino-5-Chlorobenzaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
