Isoquinolin-6-ylboronic acid(CAS: 899438-92-7)

Isoquinolin-6-ylboronic acid is a crystalline solid with a molecular weight of approximately 240.3 g/mol. It has a low solubility in water but is soluble in common organic solvents like ethanol and methanol. Chemically, it is less reactive compared to other boronic acids, making it suitable for specific synthetic transformations. It is often used as a building block in organic synthesis due to its stability and functional group reactivity.

Isoquinolin-6-ylboronic acid is typically synthesized through the reaction of 6-bromoisoquinoline with borane-dimethyl sulfide complex followed by catalytic hydrogenation. This method provides good yield and selectivity, often using Pd/C as the catalyst. Other routes include direct condensation of appropriate precursors, which can be optimized for specific applications and reactivity profiles.

Isoquinolin-6-ylboronic acid is primarily used in the pharmaceutical industry for developing new drugs and intermediates. It also finds applications in the synthesis of polymers and sensors due to its unique chemical properties. Additionally, it is utilized in the synthesis of semiconductors and other advanced materials, contributing to the development of new technologies.

When handling Isoquinolin-6-ylboronic acid, it is important to wear protective gloves and goggles to avoid skin and eye contact. It should be stored in a cool, dry place away from heat and ignition sources. In case of a spill, ensure proper ventilation and carefully clean up with appropriate disposal methods. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
