Description

2-Phenylbutyraldehyde is a versatile aromatic aldehyde intermediate with a distinct chemical structure that makes it valuable for advanced organic synthesis. Its primary importance lies in its role as a key building block for the production of pharmaceuticals, agrochemicals, and fine chemicals, where it introduces the phenylbutyl moiety. This compound is essential for research and development chemists and manufacturers in the pharmaceutical, fragrance, and specialty chemical industries seeking to create complex molecular architectures.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a phenyl-substituted butyl chain.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where its structure contributes to biological activity.
• Fragrance and Flavor Ingredient: Serves as a precursor in the creation of aromatic compounds for perfumery and flavoring agents due to its aldehyde functionality.
• Fine Chemical Production: Employed in organic synthesis for creating complex molecules, including ligands for catalysts and specialty polymers.
• Research & Development: A valuable reagent in academic and industrial R&D labs for exploring new synthetic pathways and novel chemical entities.
• Dye and Pigment Intermediate: Acts as a starting material in the synthesis of certain specialty dyes and organic pigments.

Quality Control

Our 2-Phenylbutyraldehyde is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by GC/HPLC, identity confirmation (IR), and impurity profiling, to ensure it meets the high-purity standards required for synthetic applications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, and open flame.
