Description

2-(Methylthio)-5-Pyridinyl-Boronic Acid is a high-purity boronic acid derivative, a critical building block in modern synthetic chemistry. Its primary value lies in its role as a versatile coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl and heterobiaryl structures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly in the development of active pharmaceutical ingredients (APIs) and functional organic molecules.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of novel drug candidates, especially those containing pyridine and biaryl motifs.
• Suzuki-Miyaura Cross-Coupling: A fundamental building block for creating carbon-carbon bonds in complex organic synthesis.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides with tailored properties.
• Ligand Synthesis: Precursor for creating specialized ligands used in catalysis and material science.
• OLED and Electronic Materials: Building block for synthesizing organic semiconductors and light-emitting materials.
• Chemical Biology Probes: Utilized in the creation of molecular probes for studying biological processes.

Quality Control

Our 2-(Methylthio)-5-Pyridinyl-Boronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing batch-specific results are provided with every shipment. We adhere to cGMP principles where applicable to support our clients in regulated industries.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
