Boronic acid esters represent a vital class of organic compounds, distinguished by the presence of a carbon-boron bond and an ester functional group. These versatile molecules are instrumental in a wide range of chemical transformations, particularly in metal-catalyzed cross-coupling reactions. Among the array of available boronic esters, 4,4,5,5-Tetramethyl-2-(triphenylen-2-yl)-1,3,2-dioxaborolane (CAS 890042-13-4) serves as a prime example of a compound with significant industrial and research applications.

The pinacol ester form, as seen in this triphenylene derivative, offers enhanced stability and ease of handling compared to free boronic acids. This stability is crucial for storage, transportation, and subsequent reactions, ensuring that the reagent maintains its efficacy. The specific structure of the triphenylene moiety imparts unique electronic and steric properties, making it particularly valuable in the synthesis of advanced materials, such as those used in organic electronics, and in the construction of complex pharmaceutical molecules.

For procurement professionals and R&D scientists, understanding the key specifications of such intermediates is essential. Parameters like purity (often aiming for 97% or higher for specialized applications), molecular weight (354.25 g/mol), and physical appearance (typically a white powder) are critical indicators of quality. When looking to buy these compounds, it is advisable to work with established manufacturers who can guarantee these specifications.
