Description

4-Amino-3,5-Dichlorobenzaldehyde is a versatile aromatic aldehyde derivative characterized by its amino and chloro substituents. This compound serves as a critical high-purity intermediate in the synthesis of complex molecules, where its reactive aldehyde group and halogenated aromatic core are essential for constructing specific chemical architectures. It is primarily required by pharmaceutical, agrochemical, and specialty chemical manufacturers for research and production processes.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a dichloroaniline or benzaldehyde pharmacophore.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where its halogenated structure contributes to biological activity.
• Dyestuff and Pigment Manufacturing: Serves as a precursor for azo dyes and other complex colorants, leveraging the amino group for diazotization and coupling reactions.
• Organic Synthesis & Research: Employed in academic and industrial R&D labs as a versatile reagent for constructing heterocycles, Schiff bases, and other specialty organic compounds.
• Polymer Additive Precursor: Can be utilized to synthesize functional monomers or additives that impart specific properties to polymer matrices.

Quality Control

Our 4-Amino-3,5-Dichlorobenzaldehyde is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
