Description

3,5-Dichloro-4-Fluorobenzaldehyde is a versatile halogenated benzaldehyde derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its unique substitution pattern, which allows for selective functionalization and incorporation into complex molecular architectures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to develop new active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for molecules requiring a halogenated aromatic core.
• Agrochemical Synthesis: Building block for developing advanced herbicides, fungicides, and pesticides, leveraging the bioactivity of the dichloro-fluoro substitution.
• Liquid Crystal Materials: Used in the production of fluorinated liquid crystals for display technologies, where the aldehyde group enables further coupling.
• Organic Electronic Materials: Intermediate in the synthesis of specialized monomers and polymers for organic light-emitting diodes (OLEDs) and semiconductors.
• Chemical Research & Development: A valuable reagent for exploring new coupling reactions (e.g., Suzuki, Heck) and creating custom ligand libraries for catalysis.
• Dye and Pigment Intermediate: Serves as a starting material for synthesizing complex, halogenated dyes and functional pigments.

Quality Control

Our 3,5-Dichloro-4-Fluorobenzaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory 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 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.
