Description

1,2-Ethanediamine, 1,2-Bis(4-Bromophenyl)-, (1S,2S)- is a chiral diamine compound featuring a 1,2-diaminoethane core symmetrically substituted with 4-bromophenyl groups. This compound matters as a high-value, optically pure building block for the synthesis of complex chiral ligands, catalysts, and pharmaceutical intermediates. It is primarily needed by research and development chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require enantiomerically pure scaffolds for asymmetric synthesis and molecular recognition applications.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs) targeting neurological and oncological pathways.
• Asymmetric Catalyst Ligand: Serves as a backbone for constructing novel chiral ligands used in transition metal catalysis for enantioselective reactions.
• Agrochemical Synthesis: Used in the development of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Advanced Material Monomer: Incorporated into the synthesis of chiral polymers, liquid crystals, and metal-organic frameworks (MOFs) with specific optical properties.
• Chemical Research & Development: A valuable tool compound for academic and industrial research in organic synthesis, medicinal chemistry, and supramolecular chemistry.

Quality Control

Our chiral diamine products undergo rigorous quality testing to ensure compliance with industry standards for research and process chemistry. Each batch is characterized to confirm identity, enantiomeric purity, and chemical purity. Certificates of Analysis (COA) are provided, detailing results from chiral HPLC, NMR, and other relevant analytical methods to guarantee batch-to-batch consistency and reliability for your synthetic applications.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
