Description

Butanoic Acid, 4-[[2-(4-Aminophenoxy)Ethyl](Phenylmethyl)Amino]- is a specialized organic compound featuring a butanoic acid core functionalized with a complex amine-phenoxy side chain. This unique molecular architecture makes it a valuable high-purity intermediate for advanced chemical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) and functional materials. It is primarily sought by pharmaceutical R&D laboratories and fine chemical manufacturers engaged in the synthesis of novel therapeutic agents and complex organic molecules.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel Active Pharmaceutical Ingredients (APIs), particularly for candidates targeting specific receptor sites.
• Bioconjugation & Linker Chemistry: Used in the development of antibody-drug conjugates (ADCs) or other targeted drug delivery systems due to its reactive functional groups.
• Polymer & Material Science: Serves as a monomer or functionalizing agent for creating specialty polymers with tailored properties like controlled degradation or bioactivity.
• Agrochemical Research: Employed as an intermediate in the development of new-generation herbicides, fungicides, or plant growth regulators.
• Dye & Pigment Synthesis: Acts as a precursor in the manufacture of complex organic dyes and high-performance pigments.
• Ligand for Catalysis: Can be utilized to synthesize novel ligands for transition metal catalysts used in asymmetric synthesis.

Quality Control

Our production of Butanoic Acid, 4-[[2-(4-Aminophenoxy)Ethyl](Phenylmethyl)Amino]- adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via NMR and mass spectrometry, to ensure it meets the exacting standards required for pharmaceutical and advanced research applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistent batch-to-batch quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
