Description

3-Cyanophenylacetaldehyde is a versatile aromatic aldehyde building block featuring both a nitrile and a formyl functional group. This bifunctional nature makes it a critical intermediate for synthesizing complex molecules in advanced research and industrial chemistry. It is particularly valuable for the production of pharmaceuticals, agrochemicals, and fine chemicals, where its reactive aldehyde group enables the construction of heterocycles and other complex scaffolds. Global B2B buyers rely on this high-purity intermediate for its consistent quality and role in streamlining multi-step synthetic routes.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules containing phenylacetaldehyde or benzonitrile motifs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that require specific aromatic aldehyde chemistry.
• Fine Chemical & Fragrance Manufacturing: Serves as a building block for creating complex aromatic compounds used in specialty chemicals and fragrance ingredients.
• Ligand & Catalyst Development: Employed in research and development for creating novel chelating ligands and organocatalysts.
• Material Science Research: Utilized as a monomer or cross-linking agent in the development of advanced polymers and functional materials.
• Organic Synthesis & Research: A fundamental reagent for constructing heterocyclic compounds, such as indoles and quinolines, in academic and industrial R&D laboratories.

Quality Control

Our 3-Cyanophenylacetaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC, GC, and NMR, to confirm identity, potency, and impurity profiles. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all critical quality attributes. Our production adheres to cGMP principles where applicable, ensuring the material meets the stringent requirements of pharmaceutical and advanced chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Allow the container to reach ambient temperature before opening to minimize moisture ingress and oxidation. Keep away from strong oxidizing agents and bases.
