Description

1-(p-Hydroxyphenyl)Ethylamine is a versatile aromatic amine derivative featuring both a phenolic hydroxyl group and a primary amine functionality. This bifunctional structure makes it a valuable key intermediate in the synthesis of more complex molecules, particularly in the pharmaceutical and fine chemical sectors. It is primarily sought by R&D chemists and process development teams for constructing active pharmaceutical ingredients (APIs), agrochemicals, and advanced material precursors.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of various drug candidates, including potential analgesics, adrenergic agents, and other bioactive molecules.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where its aromatic amine core is incorporated.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other colorants, leveraging its amine group for diazotization and coupling reactions.
• Polymer Chemistry: Acts as a monomer or chain modifier in the production of specialty polymers, such as epoxy hardeners or polyurethane catalysts.
• Bioconjugation and Linker Chemistry: Its amine and phenol groups are useful for attaching molecules to surfaces, proteins, or other polymers in biotech applications.
• Research & Development: Employed in academic and industrial labs for methodological studies and the discovery of new chemical entities.

Quality Control

Our 1-(p-Hydroxyphenyl)Ethylamine is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
