Description

4-(3-Bromothien-2-Yl)Benzoic Acid is a high-purity, heterocyclic aromatic carboxylic acid derivative that serves as a critical building block in advanced organic synthesis. Its unique molecular structure, featuring both a bromothiophene and a benzoic acid moiety, makes it an invaluable intermediate for constructing complex molecules with tailored electronic and steric properties. This compound is primarily sought by research chemists and process development scientists in the pharmaceutical and agrochemical industries for applications in drug discovery, material science, and the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders, inflammation, and oncology.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides, leveraging the thiophene ring's bioactivity.
• Material Science & OLED Development: Serves as a building block for organic semiconductors, light-emitting diodes (OLEDs), and conductive polymers due to its electron-rich thiophene unit.
• Ligand Synthesis for Catalysis: Employed in the preparation of specialized ligands for transition metal catalysis, enabling more efficient and selective chemical transformations.
• Chemical Biology & Probe Development: Utilized as a scaffold for creating molecular probes and tags to study biological processes and protein interactions.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects requiring specific brominated heterocyclic acids.

Quality Control

Every batch of 4-(3-Bromothien-2-Yl)Benzoic Acid is manufactured and tested under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency meet the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

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