Boronate affinity chromatography (BAC) is a selective bioseparation technique that exploits the reversible covalent binding between boronic acid ligands and cis-diol-containing biomolecules such as glycoproteins, nucleotides, and catechols. With rising demand for high-purity biologics, the global Boronate Affinity Chromatography market size is projected to reach USD 228 million by 2025 and accelerate to USD 412 million by 2033, reflecting a CAGR of 7.6% during the forecast period. This growth outlook is underpinned by rapid expansion in biopharma R&D, increasing regulatory emphasis on glycoprotein characterization, and downstream processing intensification. Synonymous termsโphenylboronate, boric acid-affinity, or diol-specific chromatographyโare converging into a consolidated market forecast that positions BAC as a critical tool in antibodyโdrug conjugate purification and proteomics workflows.
