Description

4-Amino-2-Chlorobenzaldehyde is a versatile aromatic aldehyde derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both an aldehyde and an amino group, makes it a valuable precursor for constructing complex heterocyclic and pharmaceutical intermediates. This high-purity compound is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where precise molecular architecture is required.

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 that require specific chlorinated aniline derivatives.
• Dye and Pigment Manufacturing: Serves as a starting material for producing azo dyes and complex organic pigments, contributing to color strength and stability.
• Ligand and Catalyst Development: Utilized in coordination chemistry to create novel Schiff base ligands for catalytic and material science applications.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new synthetic pathways and novel chemical entities.
• Polymer Modification: Can be incorporated into polymer backbones to introduce reactive aldehyde sites for further functionalization or cross-linking.

Quality Control

Our 4-Amino-2-Chlorobenzaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, and is supplied with a corresponding Certificate of Analysis (COA). We adhere to cGMP principles where applicable, ensuring the product meets the stringent requirements for use in regulated synthesis.

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 light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from strong oxidizing agents.
