Description

4-Diethylaminobenzoic Acid is a versatile organic compound featuring a benzoic acid core substituted with a diethylamino group, which imparts unique electronic and solubility properties. This structural motif makes it a valuable intermediate in the synthesis of advanced materials and fine chemicals. It is particularly sought after by manufacturers in the pharmaceutical, agrochemical, and specialty dye industries for its role as a key building block in complex molecular architectures.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of various active pharmaceutical ingredients (APIs), including certain photosensitizers and diagnostic agents.
• Agrochemical Synthesis: Used in the production of advanced herbicides, pesticides, and plant growth regulators where its aromatic amine functionality is essential.
• Dye & Pigment Manufacturing: Serves as a key intermediate for producing specialty dyes, particularly those requiring specific light-absorption or charge-transfer properties.
• Organic Light-Emitting Diodes (OLEDs): Employed in the research and development of electron transport materials and emissive layers due to its electron-donating character.
• Photographic Chemicals: Acts as a component in certain photographic developers and sensitizers.
• Research & Development: A valuable building block in academic and industrial R&D for organic synthesis and material science projects.
• Cross-coupling Reactions: Utilized as a substrate in palladium-catalyzed reactions for creating complex biaryl structures.

Quality Control

Our 4-Diethylaminobenzoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets exacting specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request. We are committed to providing material that supports your cGMP and ISO 9001 compliant processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
